No, the doctors don't make that final call. They advise the coach and then he has to make the decision. It's never a good idea to put a goalie in B2B nights to begin with, certainly not when they're shaking the rust off after a long time off and looked somewhat iffy the night before. But Roy painted himself into a corner when he chose not to put Reto on waivers and sent Picks down. It was a bad, bad move to keep a goalie he had zero confidence in. If by chance Berra was claimed, big effin' deal, Aittokallio, Will, and others are still in the organization. And he would've cleared easily.
Nope, I'm a big defender of Roy's but that was a huge blunder on his part. And I think he knows it.
