Pittsburgh Steelers coach Mike Tomlin says his team has plenty to work on after a lethargic loss to the New York Giants in their preseason opener on Saturday night.

The Steelers committed seven penalties, committed a series of special-teams gaffes and generated little offense in an 18-13 defeat. Their only touchdown came on a fumble recovery in the end zone in the fourth quarter, long after the starters were done for the night.

Tomlin says it would be easy to blame some of the mistakes on the long offseason, but added he doesn't accept that as an excuse.

Running back LaRod Stephens-Howling produced one of the few highlights, rushing for 40 yards on seven carries. Rookie linebacker Jarvis Jones pounced on a New York fumble in his pro debut.
