I didn't know that TEs where used so little to block in college. I do think that TE is one of the most underrated positions though. I mean, Dustin Keller is a great player already and was a great player in college, yet, goes 30th overall. They're one step behind P, K and FB.
Except for the Jets, they prefer Ken O'Brien over Marino, draft Kyle Brady over Sapp and get a FB with the 21st pick overall.
