In light of recent events, I'm thinking comparing linebackers to pit bulls might be a bad idea. Intrepid Fox end zone reporter Tony Siragusa just said Zach Thomas might be small, but "attacks like a pit bull."
In unrelated news, Cowboys second receiver Patrick Crayton appeared to dislocate his right pinky a few minutes ago. Just checked and my flight's been delayed 45 minutes, so I have a few more minutes with you.
