Tough poll.
All three have very soft hands. Imo, If they ever fight, it'll be in the playoffs.
Auston is obviously the biggest one in size, stature, and value to the team. He would ideally be face washing, and wrestling his opponent down. I'd prefer if he never fights.
Marner might be someone who can use his edgework to evade initially, land a few quick jabs and then pull off a fast, sneaky move, and drop his opponent. I prefer he never fights too.
Nylander fighting would be similar to Semin's attempt. I prefer if he doesn't ever fight too. Swedes like him, are very even keel, they really only get aggressive when a teammate gets hurt. So, say in the playoffs a Leaf got boarded in front of his eyes. Ya, I think he drops em.
Winning fights is a big momentum boost. Can be 'huge' if done by the core players like Crosby, Ovi, etc. But too much risk.
I don't know if it's crucial to need it from core players, but the beauty of the big game and the emotions all make it a possibility one day, depending on how far they go.
Will you take the risk? If you are aggressive and land the first punch, you're the hero. The roof is on FIRE at SBA. But if you miss, you're on your ass, and now the momentum has shifted, and you're injured. SBA is dead quiet.
I'd prefer 'Boston angry Hyman' out of all of them. He would destroy anyone in the playoffs.
I'd like to see 'Boston angry Hyman' vs. Tom Wilson.
