Nothing anyone can do for Raanta right now. He is just mentally shot. Maybe he can get with a sports psychologist in the offseason.
IIRC, this was sort of how he ended up out of Arizona(well that and injuries).
12 is the perfect amount. No less, no more. Don't worry though, it will be just like the premier college sport, basketball, the 13th and 14th teams will be whining each year about how it isn't fair.
Just like the bubble teams in the NCAA tournament.
