Every block is punishing....it's supposed to be, that's why they wear pads. I'm more concerned with whether or not this hit will be a foul next year vs if it is this year, or if a hit similar to this but less dramatic will soon be subject to a penalty.
Concussions, I get it, Franchise players, yeah I get that too... but changing the rules, changing how they are interpreted, altering the philosophy behind them every year because of a high profile hit or injury does just as much damage as one hit. Players, coaches and surely officials are better served by a static set of rules.
I would've received a "big stick" award had I leveled that defender when I played.
There are plenty of other sports to participate in if all this hitting is too much.......
