Must win Week 12. Who should I play in FLEX?

Well Austin is going up against a D that only has given up 8 ping TD's, Garcon is just to inconsistent, Smith you have already stated why not, Stewart I do not like the match up, Charles no no no he is not a start,Shiancoe I just don't like starting a T.E. I like Chambers he has something to prove against his old team he just might explode, And I like the ROCK he looked great at running and receiving he will have a good day. But Chambers gets it
