With Javon Walker most likely out, would you start Patrick Crayton?

I think if you're in a PPR league, Leonard will get many more carries than Crayton. Don't let Crayton's one week shine fool you - Romo's primary targets remain T.O. and Witten. Crayton could be good for six, or zero. Leonard will definitely be running the ball, and while he's not going to light the world on fire, he shouldn't be as limited against the Arizona line. Good luck.
