There is no sense hoping for someone other than West. Shaw is, how to say this, deliberate in his QB decisions.

I'd be shocked if Mills plays.  But given that Costello was at least able to practice, I think there are better than even odds that if he is feeling fine after practicing, the starter on Saturday will be Costello.

Costello was a "limited participant" in practice.  To me, that might mean he's running around but not throwing or taking snaps, or not throwing very much.

I'm also suspecting (as others have suggested, and without any proof) that the problem could be more than the thumb. He missed the offseason due to an undisclosed injury.  I can't recall, but wasn't it reportedly a bum shoulder? Something like that would sound a lot worse to everyone, read NFL scouts, than a fractured thumb, so they'd have an interest in downplaying it for him.  

Either way, I'm less hopeful for a Costello start, even though I'd love to see it happen...
