The thing is, I don't even consider him that valuable of a backup. The valuable handcuffs are decent-good RBs in great systems. When you put LJ (superb RB) in the KC system (Superb) you get a fantasy beast who was formerly a backup. When you put Turner (good RB) in the SD system as a starter (bad system) you get a mediocre RB3 at best. LT creates for himself, I don't think Turner can do that. If LT goes down that entire offense is going to flop against all but the bad defenses. The same goes for Turner if LT goes down.
ADMIN edit: please note that the overall sig limit is 12k - thanks!
