McCoy is in his sixth season in the NFL, all of which have been with the Eagles. In the first two games of the season, McCoy has run for 153 yards and one touchdown on 41 carries.
Last December, McCoy said he had a lot to do before he was in the same conversation as Sanders.
"I don't really see it as a comparison," McCoy told Philly.com. "I think Barry is probably the best running back to ever play this game. They compare us probably because of the cutbacks, but there is still a big gap between us two."
Sanders, who played for the Detroit Lions for 10 seasons, finished his career with 15,269 yards on 3,062 carries and 99 rushing touchdowns.
The Eagles (2-0) and Redskins (1-1) play in Philadelphia on Sunday.
