I last played the game of football nearly a half a century ago. By today's standards we probably played pretty dirty. One thing we never did was twist ankles. We would bite, kick, scratch and hit late, but we never went after a guys ankles. It was just too damaging. You could end a guys season. On the injuries to both Julius Thomas and Duke Ihenacho, it appeared to me as if the defender grabbed the ankle/foot and purposely rolled, thus twisting the ankle. I think that is a far worse offense than Big Vick chest bumping Luck (and Luck's ensuing academy award winning performance) or his little tap on RGIII. If they really want to protect the players, then the officials need to look at these ankle twists with as much scrutiny as QB taps. Just my 2 cents.
