Could this possible relate to how much time Robinson spent on the ice? Do we have any figures for time on ice in that era?
Robinson is 13th all-time for Total Goals On-Ice Against and 6th all-time in Total Goals On-Ice for.
Also we now have you saying he is in the top tier defensively of all-time and I beleive it was overpass or Sturm saying his Even strength numbers are right on par with Bourque's.
In Robinson's prime, his on-ice ESGF were higher than any non-Orr defenceman since expansion. Some of that is because he played with high-scoring forwards, although much of his prime extended past the dynasty years in Montreal. Looking only at Robinson's even strength points to dilute the effect of teammates, he had almost as many even strength points in his prime as Bourque and Potvin, and more than Lidstrom or MacInnis, who were more conservative at even strength.
Chelios has the lowest numbers of any post-expansion D-man drafted so far in ESGF and ESP, even after scoring adjustments, which I think reflects the fact that he wasn't as good a puck-mover and in the transition game as Robinson and the rest.
Chelios scored more points on the power play than Robinson, but less than any other drafted post-expansion defenceman. And his team's weren't particularly successful on the power play either. When he was the best PP defenceman on his team - by my estimation in 89, 90, 92, 93, 94 - his team's PP were always below-average. After that Chicago brought in a better PP defenceman, and the PP was much improved with Chelios as the second-best PP defenceman.
This is why I'm not terribly impressed with Chelios offensively at an ATD level, no matter what his scoring finishes were. Replacement level is a lot higher here, and you have to earn those offensive minutes.
I'll put up a post soon with the numbers for all modern defencemen so you guys can see where I'm coming from here.
Edit: I see Stevens was taken. Stevens seems very similar to Chelios to me. His ES scoring was pretty similar. He didn't get the PP time in his later years, but I'm not sure Chelios should get a lot of PP time here either. Stevens is also a strong contender for the best defensive defenceman of the last couple of decades. Nobody was matched harder against the opponents' best, and he played a huge percentage of his team's penalty kill.
If you just look at Stevens when he was on the Devils, he's also one of the very few "10/10s" defensively IMO. Of course, he provided very little offense with the Devils. More well-rounded earlier in his career, but I think the elite defensive version was more of an impact player.
I'm in the minority here who would take Stevens over MacInnis, but it's close.
Where do you stand on Stevens vs Chelios?
