More athlete than receiver at this juncture of his career, Robinson will have to polish his receiving skills if he's to make headway on the promise he flashed at the end of last season.
In the final four games of the 2013 campaign, Robinson tallied 11 catches for 213 yards.
Where the major problem with Robinson lies is in his route running. As ESPN.com's John Keim noted, there was a disconnect between Robinson and Griffin last season—specifically on shorter routes.
"Sometimes Robinson would get to his landmark before Griffin could throw the ball," Keim said.
Describing problems that speed receivers often run into, former Redskins receiving coach Mike McDaniel captured a weak spot in Robinson's game when speaking with Keim.
"A lot of times for guys with his speed it’s tough to manage their speed, to understand when to use all of it and when not to," he said.
Battling it out with a player like Moss, who has mastered the nuances of playing receiver, Robinson will be stuck in the No. 5 spot until he learns to harness this ability—if Hankerson impresses upon his return, Robinson may even be off the team entirely.
