The Pittsburgh Steelers used a third-round pick to add Oregon State wide receiver Markus Wheaton this offseason. He's been working as Emmanuel Sanders' backup at the X position and carries plenty of long-term upside as a deep threat. In the short-term, though, it's going to be tough for the rookie to carve out a role with the Steelers. Antonio Brown and Sanders are locked in as the starters, so Wheaton's going to have to work his way into the No. 3 role.
