If you look at a lot of the TEs who have produced in the last few years, one of the thing that really stands out is the lack of a viable WR option on the team
Gonzo in his best years was the number one guy with not much for secondary targets, same with Heap, and even Gates (although that may be changing as they've got some decent receivers recently).
If you've got really good receivers, you don't need a dominant TE.
I don't think there's ever been a team alive whose #1 need was a Tight End
