Denver Broncos receiver Eric Decker says he's been working out with new quarterback Peyton Manning for roughly three weeks and there's "no question" that Manning's arm strength is good enough to start in the NFL. Manning is recovering from a neck issue that caused him to miss the entire 2011 season and eventually forced the Indianapolis Colts to release their franchise icon rather than pay him a $28 million bonus. Manning then signed with the Broncos on March 20 following a whirlwind courtship period involving several teams.
