Last season, the Minnesota Vikings drafted an obscure rookie quarterback out of Coastal Carolina and liked what they saw during training camp. Not many people had heard of Tyler Thigpen, so the Vikings tried to slip him through waivers during the final roster cutdown period and get him on the practice squad -- an arrangement that would give them three veterans on their active roster and a youngster in development.
Unfortunately for them, the Kansas City Chiefs snapped up Thigpen on waivers. Thigpen spent 2007 on the Chiefs roster and is expected to serve as the No. 2 quarterback behind Brodie Croyle this season. For that reason, it's hard to imagine the Vikings letting go of their young quarterback of 2008, fifth-round draft pick John David Booty -- who is competing with veteran Brooks Bollinger for the No. 3 quarterback position this summer.
Judd Zulgad of the Star Tribune examined that competition.

The Detroit Lions are getting excited about the pass-rushing capabilities of third-round defensive end Cliff Avril. "His speed is exceptional," said coach Rod Marinelli, according to the Detroit Free Press.
On draft day, NFL Network analyst Mike Mayock reported that some teams were questioning the neck and back issues of offensive lineman Chris Williams. The Chicago Bears selected him with the No. 14 overall pick, and he has missed most of training camp with a sore back. "I'm real frustrated," Williams told the Chicago Tribune.
The Green Bay Packers opened camp with defensive tackle Ryan Pickett (hamstring) and Justin Harrell (back) on the sidelines. Defensive tackle Johnny Jolly practiced but is facing possible NFL discipline because of an arrest for felony drug possession.
