The Blues goaltender has been solid since joining the team, but has never been the clear-cut number one.
Let's just get this out here ASAP: the Blues' goaltending controversy is an annual tradition, like Santa Claus or the Easter Bunny, only less mythical. It is a thing that exists, because it is manufactured. It's manufactured by the fans, who can find fault with either Jake Allen or Brian Elliott (just like they could with Miller and Elliott and Halak and Elliott). It's manufactured by the team with talks of "hot hands." It's manufactured by the goaltenders themselves, to a degree, though unintentionally so.
