Penalties and suspensions is the way to go. Head injuries are not a joke and fighting only raises the chances even higher.
Reviewing games each weekend to hand out suspensions seems like an easy route to crack down on it.
I sent an angry email to NCHC.tv today that it's ridiculous the conference tournament games are not streaming. Only got a generic response that told me the third place game is streaming and they don't have the rights to the other games. I think I'm done after this year.
Just googled it myself, Free to Air. Meaning if you get an antenna, you can pick up some basic cable stations, didn't think CBS sports would be on it though.
