A new week

After a morning session in which the offense looked to do no wrong, the Steelers got under head coach Bill Cowher's skin Monday afternoon.

At one point, Cowher really dressed down rookie running back Cedric Humes, yelling at seveth-round draft pick for not running hard and looking to see where the defense is at.

Humes may be blowing an opportunity here and really needs to run hard Saturday at Arizona.

After a good start, rookie quarterback Omar Jacobs has been struggling lately.

At one point Monday, on the ensuing play after Cowher had admonished the team, yellling for, "Somebody to hit somebody," Jacobs did just that, hitting linebacker Richard Siegler right in the stomach with the ball for an interception over the middle.

I doin't think that was what the coach had in mind.

Rookie Willie Colon was playing left tackle today and looks to have moved ahead of Trai Essex and Barrett Brooks on the depth chart. Essex will be out at least a week after injuring his groin midway through the afternoon session. Brooks, meanwhile, has problems of his own after his weekend arrest.

Siegler has really flashed in coverage and could make this team as an inside linebacker over Rian Wallace, who is showing very little.
