It's the rookie quarterback crew.
With two Heisman winners and the all-time winningest quarterback in NCAA football history entering their rookie seasons, the paths that these gentlemen run down is anything but certain.
With their success as NFL quarterbacks dependent on so many factors, let's look at who will have the most immediate impact for their team.
Sam Bradford has the best shot at seeing snaps for his club.
His chief competition in St. Louis is A.J. Feeley. However, considering Bradford and the Rams agreed on a $50 million contract, I see Steve Spagnuolo trying to put their new investment onto the field mid to late in the season.
The quarterback with the second best shot at making an immediate impact is Colt McCoy.
He has proven that he has sound accuracy and his competition is veteran Jake Delhomme, who had a horrible season last year with the Panthers, throwing eight touchdowns and 18 interceptions.
McCoy has a decent shot at seeing playing time in 2010.
Jimmy Clausen also could see a limited amount of playing time in the 2010 campaign.
His competition in Carolina is Matt Moore who has only played in 16 NFL games.
Finally, Tim Tebow has the toughest mountain to climb in Denver.
This is not to say that Tebow is the worst of the four, but the Broncos have two descent quarterbacks in Kyle Orton and Brady Quinn.
Orton had 21 touchdowns and almost 4,000 yards for the Broncos last season and Orton still has promise in the NFL.
I will be very surprised if Tebow starts any game this season, barring injury to Orton or Quinn.
