I'd ride out Brazoban for as long as you can. I'm still not sure exactly when Gagne will be back full-time (if they're smart they'll bring him along slowly) and even afterwards they might rest him more than usual, which would also Brazo to vulture some saves. Long term, though, his fate is as a set-up man on LA.
I am the Master. Don't question the Master. Just do what he says and be proud.
