The Redskins are visiting with wide receiver DeSean Jackson on Monday with designs on adding him to the offense that Jay Gruden is putting together for his first season as the team’s head coach. Jackson’s arrival would presumably lead to a revision of whatever Gruden’s drawn up to this point in the offseason, but that shouldn’t lead to the coach fretting about quarterback Robert Griffin III’s ability to handle whatever comes his way. Of Griffin, Gruden says “there’s really not much that I can throw at him that he can’t do” and that the quarterback’s experience in a variety of offenses will be a valuable tool for the team to use in the coming season. “I think I’ve seen him do everything. I’ve seen him be successful in quick game. I’ve seen him be successful from time to time in drop-back game. I’ve seen him roll out and make throws. I’ve seen the play action. I’ve seen the read option,” Gruden said, via Mike Jones of the Washington Post. “Not many quarterbacks are very good on third and nine or 12. That’s very difficult time to be in, so we probably need to work on that one — but everyone does. When you see the success he’s had in different parts of the game, as far as being a normal drop-back quarterback — he’s done that. Option quarterback — he’s done that. But it’s now just a matter of packaging them all together and try to find out the best ways to attack whatever defense we’re playing.”
