We may be old at DT, but we have 3 good ones. Rookie DTs can generally play right away, and if we got Wilfork, we wouldn't need him to play right away. I think we have bigger needs and that we shouldn't pick a DT. However, Wilfork is a pretty good player and if he came to the Dolphins I think he could be a stud on our defensive line for a long time.
If we pick Wilfork, I won't start throwing things at my TV, but I won't be jumping for joy either.
