which TE?

Now with the question of QB out of the way, which TE should I start?

V. Shiancoe (MIN) vs. the Lions. With Favre still not having any confidence with his wide receivers, he might end up going with Shiancoe as his favorite target for another week. The only concern I do have is that the Vikings will be playing the Lions so it won’t be as hard for Favre to connect with his WR's

Or

D. Keller (NYJ) vs. the Dolphins. Dolphins do have one of the best D's in the league so with Sanchez's WR’s being tied up with the CB's, Keller might be Sanchez favorite target on the gridiron... 

All opinions welcomed. thanks in advance
