The 5-foot-8 Moss said he's comfortable doing it even though he has been used sparingly throughout his collegiate and NFL careers. After being selected No. 44 overall in the second round of the 2006 draft, the Giants barely used him as a kick returner - he had only 24 returns in four seasons - and even less as a punt returner.Moss certainly has speed to burn. He ran the 40-yard dash in 4.38 seconds at the 2006 combine. But he missed all of 2010 after having surgery to repair a sports hernia right before the season.Now, he said he's 100 percent healed and claims his explosiveness never left as he dealt with the injury. The Eagles offer a chance at redemption for Moss, who played in just 37 games in five years and collected just 421 receiving yards in New York because of a myriad of injuries. Understanding how to return kicks may be Moss's ticket in."You definitely have to focus," Moss said. "The first thing is getting possession of the football and catching the football. That's the main thing. Then after that, that's when talent and everything else takes over, knowing when to cut, when to make certain moves, and knowing to block."The opportunity is there. The Eagles ranked 25th in the league last year in kick returns, averaging 20.5 yards per return, with no touchdowns. And DeSean Jackson could also use a sidekick on punt returns. Moss has a rare opportunity to play receiver for the Eagles, too.At practice on Sunday, with DeSean Jackson and Jeremy Maclin both missing, Moss didn't drop a single pass and showed he could be a playmaker. In one instance, Michael Vick found Moss on a route over the middle, and Moss dived to haul in the pass. Moss' next catch came deep down the right sideline, during a 7-on-7 drill.
