They don't deserve to have to feel that way after what their own guys did for them. Yes I remember the first few times I saw Burfict as a college player. He was the dirtiest college player I had seen in a very long time - maybe ever. It's not that he would make the most brutal plays - it was that he looked like he was trying to hurt guys on every play. He has looked the same to me in the limited times I've watched him in the NFL.
The fact that nothing has changed over the years tells me one of two things: 1) He's simply a bad guy and that's who he is - OR - 2) He's just not very smart. Someone has to have gotten into his ear at some point to let him know where the boundaries are. Unfortunately his post game interview made me believe more in the former than the latter.
