On the radar: Remade receiving rotations

A player, coach or issue that should be on your radar as training camp approaches.

Every team in the division is making some sort of transition at wide receiver. The position will be one to watch all summer.

  • Arizona: The Cardinals have parted with Anquan Boldin, Sean Morey and Jerheme Urban. Rookie third-round choice Andre Roberts hasn't gotten much attention to this point and the Cardinals shouldn't need much from him in the short term as long as Larry Fitzgerald, Steve Breaston and Early Doucet are healthy. Still, this group has undergone an offseason transformation.

  • San Francisco: Michael Crabtree performed well as a rookie even after missing minicamps and training camp. Getting him on the field all summer will help Crabtree, quarterback Alex Smith and the offense. The 49ers will also be curious to see whether Ted Ginn Jr. can contribute anything to their offense. Isaac Bruce will retire and Brandon Jones will try to prove there's a place for him in the rotation.

  • Seattle: Mike Williams, a bust as the 10th player drafted in 2005, is finally in shape and serious about his career. The Seahawks can't be sure he'll continue on this trajectory, which explains why coach Pete Carroll isn't getting too excited just yet. But every indication suggests Williams could emerge as an effective player under his former college coach. Williams always had the talent. He lacked the dedication to keep himself in shape and approach the game seriously. The Seahawks also parted with Nate Burleson and drafted Notre Dame's Golden Tate as part of a positional overhaul.

  • St. Louis: Graduation rules prevent fourth-round choice Mardy Gilyard from practicing with the Rams until well into June, so the team will have to wait until training camp before getting a better read on what Gilyard might offer the offense. Might he become a difference-maker right away? The Rams face multiple other questions at the position and most relate to injuries. Donnie Avery, Laurent Robinson and Keenan Burton have had a hard time staying healthy.
