He needs to get in before the new wave tight ends become the mark to beat. Hell Jimmy Graham has played 113 less games and has 8 less touchdowns and about half his yards.

And that really just makes Witten's accomplishments that much more amazing when you consider that Graham's playing with a HOF Quarterback and he's playing with a fucking moron who thinks that a borderline HOF TE is the greatest Cowboy of all time.
