It should be noted, there are no major, long-term free agent QBs in 2010.
2010 NFL Free Agents
Kyle Orton (will be kept by Denver for sure)
Jason Campbell
Chad Pennington (old and busted)
Tavaris Jackson (far less capable than even Campbell, has failed to keep job several times)
Kellen Clemens (could not beat out Sanchez for starter, barely backup quality)
Charlie Batch (old, not leaving Pittsburgh)
Kyle Boller (no)
David Carr (MAYBE...but has he been beaten to death in his Houston years)
Daunte Culpepper (injury risk)
Rex Grossman (no way)
Joey Harrington (had chances)
Jon Kitna (ancient)
Matt Moore (who?)
Brett Ratliff (who?)
Troy Smith (great in college, good in an emergency, not starter quality)
As for college: Tebow I don't see being an NFL success. Bradford is an injury risk. McCoy looks good, I don't trust a Notre Dame QB, Pike from Cincinnati...undecided...
