I agree with mb4 on this one. Maybe he's worthy but I don't know if he makes it. Sure he's been great all-around, but he never had the gaudy stats like Gonzalez or the new breed like Gronk or Graham, and the voters might hold that against him.
Bad thing is that with passing stats only going up and up, his stats are probably going to look less impressive 10 years from now.
Of course you can blame my favorite coach for a lot of those mediocre TD numbers. It's not like Witten wasn't capable, it's that for whatever inexplicable reason he wasn't targeted.
