Stock watch: Running backs

Whether or not you're optimistic about Houston Texans running back Arian Foster, we can all agree he's no lock to return to his lofty place atop the running backs or even to play in all 16 games this season. I happen to be a fan, locking him in as a top-10 player. Others think that's crazy. Still, I'm paying close attention to what else occurs in the Houston backfield, because when we talk about potential handcuff situations, this team is near the top of the list. And the obvious handcuff was unceremoniously released on Monday.
