The 2011 NFL Scouting Combine is about to start and all eyes will be on the quarterbacks when they take the field.
There are 18 quarterbacks invited to this year's combine, but not all of them are throwing. Blaine Gabbert has said he will not throw at the event, preferring to throw to his own receivers at a private workout.
While the breakdown of who will and who will not throw and why is a good one, every quarterback will be going through the same set of non-throwing tests.
Some of these prospects will raise their draft stocks this weekend while others will fall off. A few may remain right where they are.
The NFL is a quarterback-driven league, so here's a look at how the quarterbacks rank going into the combine.
