Players to Watch in Training Camp

The Arizona Cardinals dealt Dominique Rodgers-Cromartie and a second-round pick to the Eagles to acquire Kevin Kolb in 2011, then gave him $21 million in guarantees as the replacement for Kurt Warner. Last season, though, Kolb threw only nine touchdowns and won two games. With numbers like that, many wonder whether he is worth the contract and starting position. John Skelton outplayed Kolb several times last season, creating a QB competition worth watching.
