Pead has some issues to work out, yes, but there's talent. He's more polished in the passing game than Richardson is for one. Even if not for his bonus I doubt he would be cut because they drafted him pretty early. Gotta give him at least a season under his belt before he gets the ax.
I don't expect this coaching staff to cut any players that they have drafted before they get a season in the NFL. The worst I can see happening is someone going to the practice squad. I think that was a big mistake that the previous regime did, cut guys before you even try to develop them. Rookies take time to adjust. Pead and Richardson wont be getting that many touches a game with Jackson anyway, they have plenty of time to polish their games off.
