Danario Alexander

Throw another name into the hat in an already-crowded wideout competition in St. Louis. In re-signing with the Rams, Mark Clayton brings a veteran presence with good speed and yard-after-the-catch skills.

Clayton showed he was a quick study last season in picking up the offense quickly, so learning the Josh McDaniels scheme shouldn't be a problem. But Clayton's surgically repaired knee (more precisely, his patellar tendon) isn't quite 100 percent.

If he goes on PUP/reserve, which is likely, he will be sidelined at least six weeks. But St. Louis is a good fit for Clayton and he has a very good chemistry with quarterback Sam Bradford.

Clayton is the team's ninth wideout, and the Rams are expected to keep six or seven. Danny Amendola, Donnie Avery, Brandon Gibson and Mike Sims-Walker appear to have jobs locked up. The final two or three spots will be decided from among Danario Alexander, Mardy Gilyard and rookies Austin Pettis and Greg Salas. If Clayton starts on PUP/reserve list, the team won’t have to worry about clearing a roster spot for him until mid-October or later.
