From ESPN Clayton:
Steelers working on new Bettis contract
Speculation that Steelers running back Jerome Bettis
might retire is only inspiring him more to play another season, and the Steelers are willing to work with him on his contract. Bettis took a paycut to $1 million plus incentives to stay with Pittsburgh. A similar contract might have to be worked out. For now, though nothing is official, Bettis is leaning toward playing in 2005.
And have not heard anymore about Plax. I think it depends on him. I think the Steelers feel good about being able to replace him with El, Cobb, draft, etc. I think they want to know if he is committed as everyone in the locker room says.
