Packers should have their starting left tackle (David Bahktiari), starting center (Josh Myers), starting rush LB (Zadarius Smith) and starting corner (Jaire Alexander) back this week. 3 of those guys are all-pros and they have been playing without them most, if not all, of the season. Will it help? In theory it definitely should but we shall see...
Edit: I forgot Randall Cobb al slot receiver and possibly starting right tackle Billy Turner and rush end Whitney Mercilus.
All told, that is a lot of talent to be bringing back to the field, if they are ready.
