Wasn't intended to be one, so no, it's not a joke.
But people find humor in the darndest of places.
To explain where I was coming from-
I still get a sick feeling when I think about what might have been if we had been a bit deeper at the RB position the past couple of years.
Not many teams I would like to align myself with if I were Foster and I was seeking a championship. It's quite obvious the guy isn't in a position to demand any sort of large payday. And the Steelers' fortune with RBs in December and beyond has not been good the past couple of seasons. I admit Foster would have zero ST value, which may be a reason the team would not consider him. But if that was overlooked, it would be the best three headed monster in the league in the backfield.
And given the somewhat unknowns of Bells recovery and the nature of asking Williams to deliver a performance like he did last year, again, having Foster would be nice. The team would most likely not even need him until the playoffs anyway. To have a guy of his caliber there at the ready, chomping at the bit to prove to the league that he still has it, would be a special thing to have up the sleeve.
Just my .02
