1) The on-ice officials have to make an instant judgment and usually don't have that much say in suspensions. With the Kadri hit on Sendin he was kicked out of the game but not suspended. And I'm arguing the hit is clean and you cannot show any proof of a dirty hit other then "he has an in-person meeting." I am 100% willing to admit I am wrong if there is a camera angle that shows his principal hit is to the head.
The whole point of me arguing for Wilson is because the video evidence we've all seen so far (and this is the point I am getting to) doesn't show that. However, maybe the league has a different camera angle we've haven't seen and might be why there is an in-person meeting
2) According to this,
Flames' Wideman suspension reduced on appeal, when Wideman got his suspension reduced there is an NHL/NHLPA Neutral Discipline Arbitrator and in 2016 his name was James Oldham
