It's a little hazier this year because you have one top tier running back with a hamstring injury that could be nagging (Foster), another, maybe SLIGHTLY lesser running back (only if you believe the idiots at ESPN) who could be holding out for a long time (Chris Johnson), another possible hold-out (Frank Gore) and a top 5 quarterback who is dealing with nerve regeneration in his neck (!) (Manning.)
Plus, a lot less wear and tear on the bodies. Now this could be good (gives body chance to heal, more refreshed) or bad (out of football shape. more injuries trying to get into football shape quicker.)
