Pick a RB2 in a PPR league, WHIR

[NoExcuses]

I'm committed to starting Tim Hightower as my RB1 due to his pass-catching abilities. I need to fill my roster with 1 more RB and I have 3 to choose from, they are:

Leon Washington NYJ (vs. BUF)
Reggie Bush NO (vs. NYG)
Jonathan Stewart CAR (@ TB)

and, of course, I WHIR, Thanks!
