I think it is pretty clear why Costello didn't play. Shaw doesn't think Costello is that much better and didn't have confidence that Costello had a higher probability of scoring on the next drive than Chryst. Sure Chryst was having a bad game, but he was just coming off the best game of his career and the for the first time in a month the program appeared to be stable and on an upward trajectory without a QB controversy. Every time Shaw sent Chyrst out there, he probably assumed that he would engineer a touchdown drive and overcome his poor start on the prior drives. If you have a choice between two guys that you think have a similar probability of leading a TD drive on the next possession, may as well stick the guy out there that won't give a QB controversy when he is successful and the guy who has actually played on the road. Shaw ending up being wrong as Chryst never pulled it together, but it isn't crazy that he thought Chyrst had as much of a chance of being successful on the next drive as Costello. We now have a QB controversy again as much as Shaw tried to prevent one.
