When John Harbaugh says the Ravens need to be wary of the Browns in their Thursday night game, one guy they need to be concerned about is rookie running back Trent Richardson.

Hes had a 100-yard game against the Bengals sandwiched by two less-than-mediocre performances against the Eagles and Bills.

But look at this clip, a touchdown run against Buffalo on Sunday, as the kind of thing hes capable of. Its just 6 yards, but Richardson was impressive. He slammed into the line, stopped by a wall of defenders, but immediately bounced around, just a bit outside, to find a clear path to the end zone.

Only the best backs make plays like that.

So the Ravens had better, as the NFL talking heads like to say, "set the edge" against the Browns and Richardson.
