Looking at the type of QB BB normally prefers, you're looking at someone who will be 6'4"+, smart, cool under pressure, excellent pocket presence, hard worker, a leader....
The first name up has to be Tebow, BB is in love with the kid. Can't see us spending a first rounder on him though.
I like Tim Hiller as a project better though, he lacks in a couple of areas (mobility, arm strength), but then so did some other guy we drafted a few years back, Tom something or other. He's got the size, the production (he was outstanding last year), the smarts, the work ethic - there's a heck of a lot to like in the kid and he would be my favourite. Hopefully he has a bit of a down year and stays in the 3rd-5th round range.
Zac Robinson out of Oklahoma State is another I like as a project, he's got the leadership and production, and has Cassel-like mobility.
Dan LeFevour will surely rise up Draft boards as the season continues, he's another with all the physical attributes and production to back it up.
The last one for now is Tony Pike - excellent size, tough, great work ethic, would make for another Cassel-like project.
