Wayne Gretzky dominated the scoring race in his prime like no other player. Most hockey fans, who didn't follow the NHL in his prime, can only take his statistical record at face value as a measure of his offensive dominance over the rest of the league.

However, when Gretzky played, there were other players that were sometimes mentioned in the same breath offensively. Mike Bossy was among them. While Gretzky scored more goals in the regular season, Bossy was widely considered the best goal scorer.

Why did Gretzky score more goals than Bossy if Bossy was the better goal scorer? One reason is that Gretzky played much more ice time. Bossy's coach Al Arbour and Gretzky's coach Glen Sather ran their bench in very different ways. Arbour balanced his ice time for his top 3 lines and divided special teams roles to help keep the ice time even. Sather sent Gretzky out as often as possible in all situations, and used his other top forwards very frequently as well.

I've tracked ice time for 3 Gretzky games and 3 Bossy games in an attempt to quantify the difference in ice time.

Bossy averaged 17:10 in the three games I tracked. Gretzky averaged 27:52, or over 10 minutes more than Bossy.

Most of the difference was that Gretzky played almost 1.5 times as much at even strength. Gretzky also played almost 4 minutes per game on the penalty kill, and Bossy didn't kill penalties at all. Finally, Gretzky also played over a minute more per game on the power play.

Here are the TOI numbers as a percentage of the team's ice time in those situations.

Bossy played about 30% of his team's EV ice time, and Gretzky played about 40% of his team's EV ice time. On the power play, Bossy played about 2/3 of the ice time, and Gretzky played about 85% of the ice time.

What does this mean for Bossy and Gretzky as offensive players? Let's look at Gretzky's four season goal scoring peak (81-82 to 84-85) in the regular season, and compare it to Bossy's four dynasty seasons from 79-80 to 82-83.

At even strength, Gretzky outpointed Bossy by 79%, and scored 38% more goals.

But if Bossy played 12.5 EVTOI per game, and Gretzky 17 EVTOI per game, then at EV they were virtually equal as per 60 goal scorers, and Gretzky was only ahead by 32% as a point scorer per 60.

On the power play, Bossy scored 23% more goals than Gretzky and Gretzky scored 25% more points than Bossy.

But if Bossy played 4.5 PPTOI per game, and Gretzky 6 PPTOI per game, then Bossy was actually 7% better as a per 60 PP point scorer, and was 65% better as a per 60 PP goal scorer.

We can't really compare their SH scoring because Bossy didn't kill penalties, but Gretzky was the greatest SH scorer of all time and it's unlikely Bossy would have matched him.

Overall, it's clear that Gretzky played much more ice time than Bossy. It was well known at the time, and the ice time tracking shows just how big the gap was.

If you adjust for TOI and look at per 60 stats, Bossy was clearly a better goal scorer. Gretzky was still better as an overall offensive player, but not by 50% as you might think by looking at the raw stats.


Finally, here are the more detailed TOI stats for each game.

Al Arbour:
  • Used Tonelli-Merrick-Nystrom as his #1 line at ES, and didn't use them on special teams, which balanced the TOI for the top 3 lines.
  • In one game, he changed the lines and moved the fourth liners farther up the lineup halfway through the game, which further balanced the lines. He also sat Trottier, Bossy, and Goring down halfway through the third period in a blowout win.
  • Started with 3 lines at EV, and added a 4th line in the second half of the game.
  • For defensive zone faceoffs, often replaced a winger with Goring or Trottier. They got off the ice at the first opportunity after the faceoff.
  • Rarely sent a forward out on special teams if he had just played a full EV shift, the second unit would start if needed to give the first unit a break.
  • Bossy and Trottier seemed to be less trusted defensively in the 1980 game than they were in 1981 and 1983
  • Goring played a smaller role in 1983 than he did in 1980 and 1981
Glen Sather
  • Used his best forwards, Gretzky, Messier, and Kurri, as his go-to forwards in all situations.
  • Started with 4 lines, and dropped to 3 lines halfway through the game
  • As a result, several bottom 6 forwards played under 10 minutes in each game, because they didn't play on special teams and played limited EV time.
  • Didn't send Gretzky out at the start of periods, he went out as the second or third line. Possibly to make it harder to match up against him, and easier for opponents to lose Gretzky.
  • Gretzky frequently stayed out longer and played with a second pair of wingers on the PP, and sometimes at ES
  • Always sent out Gretzky in a special teams situation, even if he had just played a full EV shift. Gretzky frequently played 2 minute shifts overlapping the start or end of a power play or PK

Looking at the number and description, even if we repeat it often and mentally understand it, it is a bit hard to fully take into account how much fitness-vo2max-endurance mental and physical Gretzky had as a tool and the toolbox, when people say he was not as physically gifted than some others big stars.

We do it for defenceman, really value being able to play high level over 30 minutes, the Keith and so on, but less so for forward.

Imagine the coach playing against Gretzky and has the game goes on he get more and more ice.... It is easier to find blazing speed or other more in your face physical advantage a great talent, but that level of endurance could go a bit against carrying all of that.

Bossy would have likely played closer to 19 minutes in the 1983 game if it was close. He, Trottier, and Goring didn't play a shift in the last 9 minutes of the game, when the Islanders led by 5 or 6 goals.

Gretzky played more shifts, and played longer shifts.

The longest shift I tracked was a 3:38 shift by Gretzky late in the second period of Game 1 against Boston in 1988. He played a full EV shift, then a full PP, then some time after the PP ended. There were 6 different Edmonton forwards out with him during this time.

Late in the second period, the score was 1-1. Esa Tikkanen, Wayne Gretzky, and Jari Kurri took the ice with 5:10 to go, following Simpson-Messier-Anderson. They played for 17 seconds and then there was a defensive zone faceoff. Mike Krushelnyski came out to take the faceoff, replacing Tikkanen. He played for 27 seconds at EV with Gretzky and Kurri, and then Tikkanen came back on for Krushelnyski. The EV shift continued until 3:52, when Willi Plett took a holding penalty to put Boston down a man. By this time Gretzky had been on the ice for 1:18.

Gretzky, Kurri, and Tikkanen stayed out for the power play, with Mark Messier joining them. Kurri played the right point. After 73 seconds on the PP, the Bruins cleared the puck, and Messier, Tikkanen, and Kurri all switched off. Kurri had played the last 2:36, and Tikkanen the last 1:47. Gretzky stayed on the ice for the remaining 47 seconds of the power play, centering Craig Simpson and Glenn Anderson. The three forwards stayed on the ice for 20 seconds after the power play ended, and then Gretzky finally left the ice together with Simpson and Anderson at 1:32, replaced by Krushelynski-McClelland-Acton.

Gretzky played with 6 other forwards during this shift. Kurri, Tikkanen, Krushelnyski, Messier, Simpson, and Anderson.

Now I'll use the on-ice plus-minus data to generate ice time estimates for Bossy's career and Gretzky's Edmonton career, and see how they compare to the three games I've tracked.

I'll estimate on-ice shorthanded goals for each player, and then get on-ice ESGF and ESGA by using TGF-PGF-estimated SHGF and TGA-PGA-estimated ESGA. I'll also remove any numbers from games where Gretzky and Bossy didn't play from the team totals.

For Bossy's career, he was on the ice for 39.9% of his team's ESGF, and 30.2% of his team's ESGA.

For Gretzky's EDM career, he was on the ice for 52.3% of his team's ESGF, and 43.4% of his team's ESGA.

For Bossy's career, he was on the ice for 74% of his team's PPGF, and 5% of his team's PPGA.

For Gretzky's EDM career, he was on the ice for 86% of his team's PPGF, and 35% of his team's PPGA.

For the three games I tracked, I had Bossy at 28.7% of his team's ESTOI, and Gretzky at 38.9% of his team's ESTOI. That's pretty close to the ESGA percentages. I also had Bossy at 64% of PPTOI and 0% of SHTOI, and Gretzky at 86% of PPTOI, and 56% of SHTOI.

So I'll make the assumption that Bossy and Gretzky played EV ice time roughly in proportion to their ESGA. The tracking data suggests they may have played slightly less ice time than that, but it's close enough. I'll also assume they played PP ice time roughly in proportion to their percentage of PP goals they were on the ice for (almost certainly not true because first units are more productive, but the error will be in the same direction and I'm not going to take the time to get a better estimate.) And I'll assume they played SH ice time roughly in proportion to their on-ice percentage of PPGA.

I'll estimate team PPTOI and SHTOI using (PP opportunities*2 - PPG)/1.1.

After all these calculations, I get:

Bossy with an estimated 14.3 ESTOI/game, 4.1 PPTOI/game, and 0.4 SHTOI/game, 18.8 total TOI/game.
Gretzky with an estimated 20.1 ESTOI/game, 5.4 PPTOI/game, and 2.7 SHTOI/game. 28.2 total TOI/game.

These are purely numbers-based estimates, but they're not far off the average of the three games that I tracked.

Using these estimates, here are the per-60 scoring rates for Bossy and for Edmonton Gretzky.

Bossy: 2.14 EVG/60, 4.11 EVP/60, 3.47 PPG/60, 7.29 PPP/60, 1.81 SHG/60, 2.04 SHP/60
Gretzky: 1.73 EVG/60, 4.82 EVP/60, 1.99 PPG/60, 7.00 PPP/60, 1.74 SHG/60, 3.41 SHP/60

Per these estimated scoring rates, Gretzky produced even strength points at a 17% higher per-60 rate than Bossy. Bossy had a slight edge in power play points per-60. As a per-60 goal scorer, Bossy was 24% ahead at even strength and 74% ahead on the power play. And of course Gretzky was a better playmaker in all situations, 57% ahead per EV60 and 31% ahead per PP60.

Again, this is all based on the official stats. I'm confident that these are in the right ballpark now that I've tracked some games for a check against the numbers.

Finally, is it 100% fair to compare per-60 scoring rates for a forward who plays 28 minutes per game against a forward who plays 18 minutes per game? Maybe not. Bossy got to conserve his energy more for his shifts, and to my eye he did play with a high motor for a star forward.

But it's clearly not fair to compare per-game scoring rates without considering big differences in minutes played, either.
