You have no problem with somebody slamming somebody down to the ground, an act that has and will kill people to this day? There's a reason real and fake wrestling are done on cushions and mats, they're trying to cushion the impact as much as they can, because things like that have a propensity to hurt people more than just haha that'll teach you to freak with me and ends up more like, "I just wanted to teach you a lesson, not snap your neck." Especially when you drop a guy flush on his head like Bennett did.
I know emotions are high, but that's no excuse to start endangering people. There's a reason the NFL fined Rolando McClain when he did his best Hulkamania on Amendola and no, I doubt that people would be fine with it if Joyner did that to Britt or Quick or if Britt or Quick dropped Joyner on his head like some rag doll. If anything I'd be angrier at them risking injuring one of our players because he got knocked on his ass, getting knocked on your ass is a fact of life in football. I know it's not fun, but getting up and body slamming somebody? Huge overreaction and Bennett is getting everything he deserves.
