PT is not playing. I think those expecting him back next week will be disappointed. Payton said PT didn't have a high ankle sprain. He is full of ####, I saw the injury. I have PT on several teams. I wouldn't play him if he was active this week, next week, or maybe even the week after that.
As for who to pick up, I think Ivory's talent level is way overrated based on one big play. Betts was described as a journeyman, but he has had success in the league. I would rather hang my hat on that than what I have seen from Ivory.
