That's a good argument but I disagree. KB's body language after the pick was absolutely horrific for a 5 year old, let alone a grown professional athlete who is displaying poor situational awareness. I 100% believe he was doing what he does best, whining, instead of thinking the play was over and expressing his emotions.
He had shown poor effort throughout the season and the attitude was getting worse. Probably the biggest standout was the Chiefs game where he just let a smaller DB rip the ball out and he looked rather indifferent to the whole thing.
I wanna watch the play again to confirm, but the play is so painful to watch at this point.
I do agree with your point about the refs culpability, just not it being 100% on them.
