I've never been sold on the idea of signing Bell because it relies on a couple of assumptions. One, that he's going to be (or at least close to) the same player that he was prior to taking a year off from football and that he was running behind the Steelers' offensive line and, two, that he's going to be any less of a malcontent after getting paid more than any running back is realistically worth.
To me, it's not about whether we can afford him. Obviously, we can. We can even afford to overpay him. It's about whether he's going to provide an even close to justifiable return on our investment. He might, for all I know, but I'm willing to place the odds of that happening at less than 50%.
