Jackson expects LeSean McCoy to get 300 carries and is thus uncertain about his own role in the offense, WGR 550 reports. "I don't know exactly what my role is going to be," Jackson said. "They say that they want Shady (McCoy) to get 300-plus carries next year. So that's a guy you're feeding the ball all the time. So I''ll be ready when my number is called." Bills running backs coach Anthony Lynn said he'd like to see Jackson's workload cut roughly in half, after the veteran had 141 carries and 66 receptions on 548 snaps last season. McCoy is clearly expected to get most of the carries, but it's possible Jackson could still handle most of the third-down work. McCoy was once among the league's most prolific receivers at his position, but he caught 28-of-37 targets for just 155 yards and no touchdowns for the Eagles last season.
