He is the only leaf with a game winning goal in round 2 if you are looking at game impact.
To be clear, Marner has double the 5x5 production of points than Willy and 4x the primary assists.
Driving play is a metric we arent talking about. There is an interesting stat on moneypuck called created xgoals minus actual xgoals.
There are 7 players in the negative.
Rielly #1 in the positives, Marner tied with a few players at #2 with a few players with the forwards including Matthews and Knies
Willy is part of the group of 7. In that group...Tavares, O'Rielly, Kerfoot, Jarnkrok, ZAR and Acciari.
Bunting had a net of zero
So if Willy aint scoring a ton, what was he doing instead of that to drive play? He literally only had 1 more goal than Marner.
