I think it is simple: He is a Rookie. We will have changes to our TE line-up in the future and he may take on a bigger role in response to his development, health, changes to personnel and of course, injuries. I think if healthy, Willson is a better H-back right now; he was stating to look great in that role before getting hurt. He may leave next year. Jimmy may leave (win SB first please) to save $$, or make more $$ elsewhere after being a SB MVP (I hope).
