There isn't anybody better than Kevan?

Kevan Barlow? Is he really the answer at RB for the Steelers? If it was TJ Duckett, Ladell Betts, Ron Dayne, or another already now signed, but missed opportunity, big back, I wouldn't even question the move. I don't like busting on Pitt guys because I like to see them do well. But, Barlow has not been good for a while now. He has problems holding onto the ball and he was down right bad with the Jets last year. I know the Steelers need more RB depth, but I'm just very skeptical that this guy is the answer. The only way I can accept him as a Steeler is if his role is third or fourth string -- insurance in case either Parker or Davenport go down with an injury.
