Chryst didn't play poorly enough to lose the job, Costello didn't play well enough to take it from him.

Well, that needs to be taken with a brobdingnagian grain of salt.  Costello only had what, two series?  Whatever it was, he didn't have nearly the number of opportunities Chryst had.  Chryst was 50% completions.  This is who he is.  Costello was 60% completions.  This is who he is.  When you consider Costello also runs better, how does it not make more sense to give Costello more opportunities given he so clearly has more upside.
