Seems to me that Zidlicky is biting on Kessel's fake move to chip the puck via the boards, it's a brilliant individual effort on that goal.
Still think Gionta should know better than chasing the puck, he should know that move could easily put him on the wrong side of the puck. As for Henrique I can't see how he can manage to angle him without a massive interference call. There is no way he can do that with the speed Kessel has coming in.
Had Gionta protected ice instead of deer hunting like a fool, his d man could have had the freedom to come down deeper and Kessel wouldn't have all that space.
