re: Drop D. Henry for one of these 3 RB's

I think you'd be giving up on Henry a little early. Given the offensive philosophy of the Titans, he's an elite handcuff and could eventually be in a 40/60 carry split regardless of Murray's health. They've also involved him in the passing game. You'd be dropping him for another backup that probably has a lower ceiling. You can roll with Anderson and Langford and do fine at RB. Just my 2 cents
