As the Redskins go about installing their offense under new coach Jay Gruden and new offensive coordinator Sean McVay, one thing has been clear during training camp — they’ve got a lot of weapons at wide receiver.

“We are very fortunate to have the receiving corps that we have,” Gruden said. “I feel really good about where we are.”

And why not? Gruden has the NFL’s leader in receptions in Pierre Garcon, the speedy DeSean Jackson, versatile Andre Roberts, wily veteran Santana Moss and a host of players jockeying for what could be six receiver roster spots.

“It’s very dangerous and it’s very scary,” Jackson said. “I’d rather be on the team that has all the weapons.”

The surprising acquisition of Jackson in April helped lead to the glut of receivers. Jackson, who had 1,332 receiving yards in 2013, has a chance to prove that last year’s numbers weren’t just a result of the Eagles’ system.

“What I look forward to is to continue to go out there and be known as one of the best playmakers in this league,” he said.

The person probably hurt most by Jackson’s arrival is Roberts, who signed a four-year deal in March to slide into the No. 2 receiver spot. But the former Cardinals wideout is taking everything in stride.

“We’re all out here to work together,” he said. “I think all the receivers love [Gruden’s] offense. I think we’re going to be throwing it a little bit more and we’re definitely going to be helping the running game out.”

The bottom of the receiver depth chart holds a certain amount of intrigue as well. With Leonard Hankerson on the physically-unable-to-perform list, Aldrick Robinson has stepped in and performed well — snagging a long touchdown pass during Monday’s practice with the New England Patriots — while rookies Ryan Grant and Rashad Lawrence have shown flashes.

“Aldrick has had a great camp,” Gruden said. “He’s made big play after big play and that doesn’t go unnoticed. We have a lot of guys that are competing for the four, five, six and seven spot.”

Are there enough balls to keep everyone happy? That’s to be determined, but right now, it’s a good problem for the Redskins to have.

“The sky is the limit. Honestly, it is,” Jackson said. “And at any given time a defense is going to have to be accountable for multiple guys — not just one guy, not just two guys, but four or five guys every play.”
