A lot of them never pan out.

See here...this article is a bit dated, but gives a good snapshot of the crapshoot that is QB recruiting: http://mgoblog.com/mgoboard/where-are-they-now-2009-elite-11-qbs-including-gardner-bolden-boisture

Blake Bell (committed to Oklahoma) - RS Soph backup who plays Tim Tebow role for Oklahoma in red zone with Landry Jones entering his final season.

Joe Boisture (committed to Michigan State) - retired from football.

Robert Bolden (committed to Penn State) - Junior who lost starting QB to Matt McGloin last 2 years. Not attended summer workouts and classes this year and future status uncertain.

Tyler Bray (committed to San Diego State) - Switched commitment to Tennessee. 2 year junior starter at Tennessee. Should be one of the elite QBs in college football this year.

Barry Brunetti (committed to West Virginia) - Junior who transferred last year to Ole Miss. Supplanted as starting QB midseason last year and now battling for starting job again.

Devin Gardner (committed to Michigan) - obvious.

Jake Heaps (committed to BYU)- Junior who just transferred this year to Kansas along with Dayne Crist. Charlie Weis: the refugee camp for failed Elite11 QBs?

Austin Hinder (committed to Cal) - RS Soph not on the two deep depth chart.

Nick Montana (committed to Washington) - RS Soph who just transferred this year to JC.

Jesse Scroggins (uncommitted) - RS Sophomore battling for backup position at USC behind Matt Barkley.

Phillip Sims (committed to Alabama) - RS Soph who just transferred this year to Virginia.

Chandler Whitmer (committed to Illinois) - RS Soph who transferred to JC last year due to lack of playing time (behind Scheelhaase) and just enrolled at UConn. Maybe Michigan sees him next year in 2013 when play at UConn.
