If you drafted LJ as your RB1 or RB2 & understanding that he is such a risky candidate and playing for an AWFUL Chiefs team (bottom 10 in the league), you should have taken an *early RB3* to provide much needed depth & security at the crucial RB position. Let's say hypothetically your draft went like this:1.07 Portis2.06 LJ3.07 Turner / Reggie Bush / Edge / McFadden / J Stewart4 WR15 WR2 6 WR3/QB/TE etc ~Again by picking LJ you tacitly agree to play your RB2 on matchups & need to hedge your bet in case he didnt return to form after injury. If you're just in a 10 team league there might be serviceable options available for trade as a few teams prob have 3-4 startable RB2 options, or even you might find some scraps on the waiver wire (Benson, PIT's rb of the week? etc).
