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 a back on his fourth team in three years in Carlos Hyde. If Thompson can outperform either in camp, he could find himself with a significant role in one of the league's most potent attacks. Read Past Outlooks
