He gets the jump on him and starts throwing before Miller even gets his gloves off. I'd say it's pretty similar to be honest. The only difference is Wilson gets dusted towards the end once he realizes he's dealing with Kevan Miller.
He certainly gets the jump on him, I'm not denying that, but they're two very different circumstances nonetheless.
Miller left his position and physically engaged with Wilson behind the play in some pretty typical "we might fight" behavior. They collide, then square up and look each other in the face. Wilson absolutely starts throwing too early, I would prefer seeing both players drop gloves first, but at least they're both aware of one another. For better or worse, when Wilson throws the gloves and engages at least Miller gets his stick out there, he's clearly capable of putting up some manner of defense.
Marchand has his gloves off and is reaching for Eller's head before he's even in front of him. He's got Eller's helmet off and is throwing blows at the head before Eller is capable of defending himself at all.
