If Bussi has a great camp the B’s will just carry 3 goalies IMO…at least for a while. Swayman has never started more than 45 games in a season and Korpisalo will have a chance to rebound as a backup on a good team. I think you can still sneak some starts in for Bussi as well.
Much like Montreal kept Primeau up last year and got both him and Allen starts behind Montembeault. At the deadline you may be able to leverage either a rehabbed Korpisalo or a promising Bussi with some NHL games under his belt into other assets.
