So at what point does Indognito make sense?

Scott, I agree that in hindsight keeping Joseph would be a nice luxury even as I am not second guessing why the Bucs did what they did.  At the same time, for the life of me I don't understand the downside of bringing in Incognito.  If he helps us and has eaten some humble pie (wanting to get his career on track again), the controversy will die down in a couple weeks, and if he even begins to act out, the players get on him and we cut him with very little loss in cap revenue.  Isn't the fact that we are understandably reading articles on if we had kept Joseph almost exhibit A that it's time to try an upgrade?
