He's got 9 points of in his last 5 games since coming back, pulling his PPG to 2.6. Considering the injury and WJC hangover, that's pretty solid. I expect him to score at about a 2.3-2.5 ppg pace to finish the season, maybe ending up with 120-130 points in 50 gp. If he was able to play 60+ games, he really would have had a shot at Crosby's numbers. Without injury he probably maintains a slightly higher pace, and maybe goes 62 gp 155 - 170 points.
At this point, I don't think he's got much of a chance to catch Marner, and may struggle to even beat Strome.
Whats crazy to think about is that he could end up being the best NHL prospect and player to never lead his junior league, or even junior team, in scoring. That's insane, considering he has a higher point potential than Crosby did (at least IMO).
I still don't see him as quite on 87's level as a prospect (97 has a lower floor and expected level), but the ceiling is there based on his advantages in skating and reach, and the fact that he's not as physically mature as 87 was at the same age (so he could potentially fill out more).
All that said, nothing is stopping him from catching fire his last 27 games and scoring like 80 points. Marner is on pace for a huge year (150 points), but he could slow up and end up around 135. Hopefully McDavid can put some pressure on him and make it an interesting race.
