I've never done a dynasty league, but I've often watched interviews to see what players are like. Funny you mentioned it, but I did just watch ones with Gore and Lynch a few days ago lol. I would still draft either of these guys, but I have passed TO before because he acts like such an idiot. Even as a Giants fan, I can't completely like Plaxico because he's a headcase and his interviews make him sound like an idiot.
True story - I was at my fantasy draft I do each year with some friends of mine a few years back and my buddy picked TO in like the 2nd or 3rd or whenever it was. I told him that TO is such a moron and he'll end up suspended or something. Sure enough, 30 min. later ESPN shows him riding the excersise bike looking like Lance Armstrong. My buddy shook his head and said I can't believe I drafted this idiot lol.
