PITTSBURGH -- The Pittsburgh Steelers lost their second preseason game to the Tampa Bay Buccaneers 17-14 in a sloppy affair. However, while the team sat most of their starters, the Steelers did put some of their rookies, such as Derrick Harmon and Kaleb Johnson on the field for a second look.

Pittsburgh first-round pick Derrick Harmon earned his first sack of the preseason by swallowing up Trask for an 11-yard loss. Running back Kaleb Johnson, a third-round selection, took a significant step forward, rushing for 50 yards on 11 carries and showing flashes of the cutback ability that made him a star at Iowa.

The Steelers haven't played their top three cornerbacks yet in the preseason. This has been a great chance to evaluate the depth on the roster, but it hasn't been great. Jalen Ramsey, Joey Porter Jr., and Darius Slay are going to have a heavy workload unless a player or two behind them steps up.
