That twisting of the ankle, foot is total bush league. Norman is a clown. I have a real problem with that, because it looks like deliberate intent to injure, and its after the play.
Desean Jackson has been doing that stuff for years, I guess that's part of it anymore, he sure isn't the only one. Prescott didn't seem fazed by it since they exchanged jerseys after the game on the field (another player ritual I can do without, but whatever).
I will say, when you get up after nearly every run and do that "feed me" motion (hey I love Zeke as much as anyone), you are probably going to get some taunting and stuff like that right back at you.
