Some made a good post on HfBoards :
" When Jokinen passed the puck it took a total of 600 milliseconds until he was hit by Cowen.
Heres some pics to show you:


The NHL states this:
UPDATE: A league source provided explanation into the department of player safety’s ruling. Using the NHL’s software, the source said, the league had the hit timed at 0.467 seconds after the puck left Pacioretty’s stick. That puts the hit under the NHL standard of 0.5 seconds for a late hit and well below the 0.6-0.7-second threshold the DOPS uses to determine whether late hits warrant supplementary discipline.
So if we go by that, Cowen was in the second threshold, whatever that means. He was .1 second late, it wasnt "WAY" late like a lot of you are saying. "
So yeah, the suspension is a complete joke and I would be really mad if the Sens were still competing for a playoffs spot and Cowen was a usefull player.
