I've wondered the same thing myself.
As near as I can tell, the answer is that Bradford won't get the job and the reason is that he's their most reliable set-up guy by far and they need him in that role. If you go down the line, all the top closers throw heat, so Harden seems like an obvious choice as a possible closer. It may also be--and I don't know if this has happened--that Bradford has already made it clear to A's coaching that he doesn't want to close.
Bluto: Over? Did you say over? NOTHING is over until WE decide it is! Was it over when the Germans bombed Pearl Harbor? HELL, NO!
Boon: Forget it, he's rolling.
