Let's break some of this information down a bit here:
On the surface, round 2 of the playoffs has Willy, Matthews, Marner, Tavares, Knies, Domi looking like this:
| G | A | Pts | EV Pts | Shots | Hits | Blocks | Hits Taken | Takeaways | Giveaways | PK ToI |
Nylander | 3 | 3 | 6 | 5 | 19 | 3 | 3 | 9 | 1 | 5 | 0:04 |
Marner | 1 | 4 | 5 | 4 | 8 | 17 | 11 | 14 | 1 | 7 | 14:12 |
Matthews | 1 | 3 | 4 | 4 | 26 | 19 | 6 | 8 | 6 | 8 | 10:56 |
Tavares | 2 | 0 | 2 | 1 | 23 | 13 | 7 | 11 | 1 | 9 | 0:05 |
Knies | 2 | 2 | 4 | 4 | 15 | 19 | 4 | 7 | 1 | 6 | 11:47 |
Domi | 2 | 3 | 5 | 4 | 11 | 6 | 1 | 5 | 2 | 5 | 0:00 |
Under the surface, then things get a bit more interesting.
Individually:
| ToI | Shots | Expected Goals | Scoring Chances | High Danger | Rebounds Created | Offensive Zone Starts | Defensive Zone Starts | O. Zone Faceoffs | D. Zone Faceoffs |
Nylander | 132:26 | 19 | 1.82 | 17 | 8 | 0 | 32 | 8 | 58 | 30 |
Marner | 154:34 | 8 | 0.6 | 6 | 1 | 2 | 42 | 39 | 67 | 69 |
Matthews | 143:34 | 26 | 3.33 | 26 | 14 | 7 | 40 | 37 | 67 | 69 |
Tavares | 134:19 | 23 | 2.76 | 28 | 14 | 8 | 27 | 11 | 50 | 37 |
Knies | 137:16 | 15 | 3.65 | 21 | 15 | 2 | 34 | 23 | 54 | 44 |
Domi | 87:37 | 11 | 1.21 | 14 | 4 | 2 | 14 | 10 | 22 | 24 |
As a line:
| Shots For | Shots Against | Goals For | Goals Against | Expected Goals For | Expected Goals Against | Scoring Chances For | High Danger | Scoring Chances Against | High Danger |
Nylander | 78 | 82 | 7 | 7 | 10 | 6.61 | 83 | 42 | 74 | 25 |
Marner | 67 | 58 | 7 | 9 | 9.55 | 5.66 | 75 | 40 | 79 | 23 |
Matthews | 67 | 54 | 7 | 7 | 9.9 | 5.59 | 77 | 42 | 74 | 20 |
Tavares | 77 | 83 | 6 | 9 | 10.42 | 6.36 | 75 | 41 | 70 | 27 |
Knies | 63 | 50 | 7 | 10 | 9.11 | 6.54 | 72 | 37 | 79 | 24 |
Domi | 39 | 42 | 5 | 2 | 4.2 | 3.82 | 32 | 13 | 42 | 17 |
What do these numbers show?
Well, they clearly illustrate a set of players whose job was to do nothing but generate offense.
It shows a different set of players whose job was to create offense, but also to stymie the offensive line of the opposition, and to kill penalties.
What it also shows, clearly, is that the set of players whose entire job was to generate offense, barely, if at all, outperformed the other set of players in that 1 duty they had.
As it pertains specifically to Nylander, these numbers paint a picture of a player:
1. Entirely offensive usage
2. Generally stayed in the perimeter with lots of shots and 0 rebounds created
3. Did not engage in physical play
That's purely from stats. The eye test showed that Nylander was very much engaged offensively, always looking for quick breaks, and generated quite a few breakaway chances.
Hmm, that seems to reinforce the idea gained from the stats.
Lastly, how did these players get matched up in the series?
Florida currently has 2 Selke finalists on that top line of theirs - Sasha Barkov and Sam Reinhart.
Let's say that the Leafs' top line faced off against those 2 players for 78 minutes each, while the 2nd line faced off against them for just over 32 minutes.
Sam Reinhart scored 50 goals last year. Barkov is a 90+ point player. They were neutralized by Matthews, Marner and Knies. Sure, they neutralized the Leafs' top line as well, and thus the biggest weapons for each team were essentially taken off the board.
And yet, the 2nd line for the Leafs, while facing drastically lesser opposition, did not fare well.
