emergency back - which to pick up, please help

[lunchbox]

deangelo williams hurt, joseph addai hurt, mike hart hurt, reggie bush hurt, i have one healthy running back and need to start two, who should i drop hart for? I don't like lynch's matchup, donald brown is starting but was I'm not sure how effective he'll be, mcgahee is second fiddle to rice but might get enough to be worth it over the other two...

Willis McGahee (vs. Miami)
Donald Brown (at Philadelphia)
Marshawn Lynch (vs. NY Giants)

gotta get d. brown

[scientology]

I'd lean towards Brown because he will likely get more touches then McGahee but there is still an injury concern with him. Colts signed some guy off the practice squad likely to back up Brown since Hart and Addai are out. McGahee has a good chance to get some touches even with Rice there in a good match up. Tough call here but I'd steer clear of Lynch.
