Former NFL quarterback and current ESPN analyst Trent Dilfer believes the NFL should have a developmental league, Dan Hinxman of the Reno Gazette-Journal reports.

"The NFL is not a developmental league. It should be," Dilfer said. "If I was a coach (and the NFL had a developmental league), I would take a Colin Kaepernick every year."

Kaepernick is the starting quarterback for the University of Nevada, and has completed 55.5% of his 912 pass attempts for 7,076 yards, with 61 touchdown passes and just 16 interceptions. Late last week, Kaepernick was added to the Johnny Unitas Golden Arm Watch List for the 2010 season.

While there are no questions about his athletic ability (Kaepernick has 2,906 yards and 39 rushing touchdowns), Nevada's "Pistol" offense makes it difficult for NFL teams to get a read on what kind of NFL quarterback he'd be. At 6-6 and 220 pounds, NFL teams may view Kaepernick as a wide receiver or a "move" tight end, flexed off the line of scrimmage.

"My impression is he is like a lot of college quarterbacks we evaluate these days," Dilfer said. "Because of the system, he's hard to judge as an NFL player. From a skill-set standpoint I think he has all the tools, but his instincts and mechanics probably need to be refined. That doesn't mean he can't do it. He'll just be looked at as a project."
