In an interesting move Thursday, the Steelers released running back Gary Russell, their primary kickoff return man and short-yardage specialist in 2008.
The move was announced at the same time as the team announced it had re-signed quarterback Charlie Batch.
It's likely that this was a salary cap move. With the signings of James Harrison and Batch this week, the Steelers had to be tight against the cap.
Russell wasn't making a lot of money, but the $450,000 or so in base salary he would have earned was likely used to sign Batch.
It also shows how much confidence the Steelers have that running back Rashard Mendenhall will be completely healed from the broken shoulder he suffered early in the 2008 season.
