I guess I can see the temptation to start Caddy, but I wouldn't.
Stick with the guys you picked the earliest:
Andre and Roddy are absolute no brainers. Under no circumstances would I ever consider Braylon or Burleson over either player, regardless of the matchup.
At RB, stick with Forte, who will still be the focal point of the offense even with a tough matchup and Kevin Smith who was productive even when Detroit was going 0-16. Caddy may turn out to be a one week wonder, and at best is one half of a RBBC. The other two are the horses.
