Redskins fans will be hoping this crop of receivers are an improvement over last season's group, and if they are, it should help rookie QB Robert Griffin III develop.

Newcomer report: Pierre Garcon and Josh Morgan were signed as free agents and both need to provide yards after the catch. Morgan hasn’t practiced much because of a sore hamstring (though he’s scheduled to return Monday). Garcon hasn’t had a lot of explosive plays in recent years (in his last 137 receptions he’s only had 16 for 20 or more yards). He’s caught one or two deep balls in full-team work this summer. Morgan needs to show more explosiveness coming off last season’s ankle injury. 

Rejuvenation: Santana Moss looks spry, having lost 15 pounds. He’s a good fit in the slot, but at 33 there’s a concern about how he’ll hold up over a 16-game season. That’s why it’s important that players such as Morgan and Hankerson can help. 

Who should be safe: Receiver Anthony Armstrong had a good season in 2010, averaging 19.8 yards on 44 catches. He provides toughness, blocking and special teams play. With a strong-armed quarterback who can throw deep, Armstrong should have more opportunities.

On the bubble: The Redskins likely will keep six receivers – they kept seven last year, but one was returner Brandon Banks. Coach Mike Shanahan said Banks, or whomever the returner is, must show they can contribute as a receiver. Thus far Banks has looked more explosive than the others in this category. Banks has caught a couple deep passes, but also has shown he can be tough to jam at the line and can get open underneath. However, at 5-foot-7 size and durability is an issue. Terrence Austin has looked sharp, thanks to excellent footwork. It’ll be tough to cut him loose, but he must offer something the others don’t and right now it’s not evident that he does. Second-year Aldrick Robinson is improved, but he hasn’t stood above the others in this competition.

Intriguing: Newcomer Dezmon Briscoe is still learning the offense, though he said it was similar to what he ran in Tampa Bay. Briscoe hasn’t yet used his size to his advantage in practices, at least not consistently. He’s not a burner, but he could help in the red zone as a bigger target (6-foot-2). He averaged only 2.9 yards after the catch in 2011; YAC, or rather the lack of it, was a major issue with the Redskins coaches after last season.
