Yay a regulation win!
I didn't like the coaches challenge from the beginning and the challenging of offisde really bugs me.  You now have a game where the linesman can eliminate a scoring chance by mistakenly calling a play offside yet you are calling back goals if the same linesman mistakenly calls a play onside.  It would be a better rule to not call offside on the ice at all, just review ever goal to see if it was.
