The TE getting the best reviews from multiple observers is Andrew Quarless (6'4", 248, Penn State, 33.8" arms, 10" hands, projected 4.74 forty).
"Surprisingly fluid and graceful; makes good adjustments to the situation and to the throw; explosive off the line, deceptively fast; smooth route-runner, consistently open for hot read, very good hands, shields catch from defenders well; aggressive blocker, breaks off his own route properly to block for another receiver." (Compiled quotes).
By contrast, Villanueva is said to be slow with suspect hands. OTOH, it would be hilarious to watch a 5'9", 177# CB try to cover (or tackle!) a guy 6'9", 277#. It would be some epic fail for the defense to even accidentally match up that way, but still.
Quarless was originally projected to the 7th round, now maybe up to 5th round. Could be even higher after the game.
