Alright, so I had to dial this play up to see for myself. I’m no Hendrickson or Bengal apologist, but I can see why no penalty was called or no fuss was made. Dion sort of spins 91 to the ground, and in the process of rolling over from his frontside to his backside his legs follow suit and they miss Allen completely. As he completed the rolling motion and gets to his backside, did his left leg straighten out a little bit more than normal? Maybe, but it was not a leg whip imho. Looked like typical pocket trash.
