Sorry to all the Tom Wilson haters but Wilson didn't get suspended because it was determined it wasn't a suspendable play. I'm sure DoPS wanted to but they can't really change another rule for Tom Wilson.
Tom Wilson got 4 mins for roughing a 10 minute misconduct and a $5000 fine. That's about the max they could give him for that without changing the rules.
Demonstrably false.
The fact that you said he got penalized four minutes for roughing says enough - he broke a rule [Rule 51.1]. Why do any rules need to be changed when he already broke a rule???
Could also hit him with Aggressor [Rule 46.2] ruling. Both roughing and aggressing have been the basis of suspensions before, and the NHL rulebook even explicitly says, DoPS does not even need a penalty to take supplemental discipline - their ruling can be
supplemental to any penalties on the ice, or can even supersede/contradict any previous calls [Rule 28].
$5000 is not even the max fine they could have given him. If they could've been bothered to pick up the phone and offer him a telephone hearing, they could have fined him double that [CBA 18.7 (b), (d)].
To say they would need to make up a rule, change the rules, or that that was all they could have done is asinine.
