Pretty straight forward stuff, do you play Ben this week against Philly? Even if he was healthy, or is healthy, he wouldn't get more than a series or two, so do you risk it coming off that twisted ankle or stepped on foot or whatever he says he's got?
I say at this point why bother, just let the other 3 take the reps, especially seeing what Jerrod Johnson can do. Maybe Leftwich starts in the first quarter, Batch for the 2nd and then like Johnson finish the game. It's not likely that Ben would be injured in this game anyway but you never know.
