What is TWill not doing to hold his feet to the fire? He's done well with the targets he has gotten. He doesn't have a bad attitude, he doesn't drop a lot of balls, and he doesn't make many mistakes (needed to run out of bounds 2 years ago).
I forget which game it was, but I believe it was Aikman who was pointing out how Twill was consistently getting open but Dak wasn't looking in his direction.
Personally, I think TWill should have been targeted more. I know a lot of people don't like him probably because of his body catching, but I think he has been under-utilized and believe he would have much better numbers elsewhere.
