Redskins beat writer Mike Jones on the team's receiving corps:
There’s no question the starters are Pierre Garcon and DeSean Jackson, with slot man Andre Roberts joining them in frequently-used three-receiver sets. But the spots behind them remain up for grabs. Santana Moss had been the slot guy, but now returns on a non-guaranteed deal and will work to compete at whatever spot he can. Aldrick Robinson had served as the deep threat and backup to Garcon, but hasn’t been the most consistent or versatile guy in the past. Leonard Hankerson has seen some time in the slot, but might not fully recover from anterior cruciate ligament surgery until late July/early August. Fifth-round pick Ryan Grant and undrafted free agent Cody Hoffman will push veteran teammates who are on the bubble. Grant doesn’t have the speed that Robinson has, but he’s bigger, and he’s more versatile with the ability to play on special teams, which Robinson does not. Last weekend, Grant lined up both on the outside, and in the slot. He also served as a jammer and gunner on special teams. Gruden praised Grant, saying he played like a 10-year veteran at the minicamp. Meanwhile, Hoffman is the biggest receiver on the roster at 6-foot-4, 210 pounds, and he too plays special teams, having stood out in college as a return man. He also is a precise route runner with good hands, according to Gruden. The veterans could have to work extremely hard to fend off these two rookies.
The top three spots seem settled with Garcon, Jackson and Roberts. From a redraft fantasy standpoint, that's all that really matters.
