i don't believe that tight ends change games. i would say that they are a luxory, and if you are stocked everywhere else, you can take one.
a team with as many needs as us has no business taking a tight end in the first round. we had a good tight end, we just let go. didn't even get anything for him....
Shockey and Heap seem to do a good job on their team, and of course Gates and the Gonz does a great job on their team, and I'm sure Winlow will make a big different with Cleveland starting this year.
