If any rookie running back is positioned to be a sleeper this season, it might be Thompson. With a fire-hydrant build at 5-8, 200, the sixth-round pick out of Utah State runs with impressive power and a low center of gravity, making him a threat to bulldoze his way for yards between the tackles. He also has good hands and could develop into a solid route-runner, important traits in an Andy Reid offense. He hasn't shown much in the way of speed or elusiveness and might not be a big-play threat, but the Chiefs' backfield is topped by a player with minimal experience as an NFL lead back in Damian Williams, along with an aging LeSean McCoy. If Thompson can outperform either during the season, he could find himself with a significant role in one of the league's most potent attacks.
