His skate is clearly caught in Kessler's leg and he's definitely trying to tug it free.
I don't see conclusive evidence that Pronger "stomped" (which connotes an intentional, malicious act) on Kessler. Clearly, though, Pronger stepped on Kessler ... which, IMO, is a result of Pronger trying to get free.
Still, the drumbeat out of Canada won't rest until there is a suspension.
I think it will be 10-15 games. But, I think this whole thing is a joke and it smacks of advocacy journalism by TSN in a clear attempt to get Pronger suspended. It's utter BS that he was informed there was no suspension only to have it re-opened. If the Ducks had played last night, it would have been too late ... so here is yet another victim of the crappy packed schedule at the beginning of the season.
BTW, here is a link to the incident as part of Dreger's "report" on it.
