I beg to differ/disagree. To me - yes my opinion - looking at the shots both in real time and slo-mo it was deliberate. The first one could have been accidental, the second one was almost certainly intentional. I stand by my opinion that based on this incident and his long history of player endangering violence which he has been penalized and fined for, he ought to be drummed out of the NFL.
If deliberate, how does one know where to step when they're looking down field and moving backward?
