4. It wasn't a crisp performance from the Patriots who played Saturday, but several youngsters stood out. On defense, rookie Byron Cowart got off to a raging start, bulldozing veteran guard Roger Saffold for a monstrous sack of Mariota on the game's first series. Later, third-rounder Chase Winovich played with his hair on fire, destroying Tennessee's backup tackle with a bevy of rush moves. A man with an endless motor, Winovich picked up five tackles, a sack, two QB hits, two tackle for loss, forced a hold, and added a bevy of other pressures. In the secondary, second-rounder JoeJuan Williams was stellar in coverage early.
On offense, left tackle Isaiah Wynn, who missed all of last season, played three series and looked solid. The LT anchored well in pass pro. He can improve in run blocking, but for his first appearance, it was positive. Receiver Jacobi Meyers continued to eat up corners off the line of scrimmage (6/82). Rookie running back Damien Harris got the bulk of the workload in the backfield and responded well in both the run and pass game, earning 14 rushes for 80 yards and four catches for 28 yards. Harris displayed great vision on a 20-yard scamper, toughness to power through arm tackles, and good route running to find free space. Backup QB Jason Stidham also continued his stalwart preseason, completing 74 percent of his passes for 193 yards and a beautiful arching back-shoulder TD.
