To be fair ... from the highlights that game looked like a non-contact league that favors shooters ... the only defense for a goalie is if a defenseman gets a stick in front of a shot. It wasn't just Swayman the other goalie was hung out to dry as well.
The best thing Swayman could do would be to keep his mouth shut, avoid the media, and not talk about anything. Don't talk about these games, don't talk about the Bruins, don't talk about his play last season or what he hopes for next season ... just keep his mouth shut and focus on getting his game back.
Then, if he is still with the Bruins, let his play talk for him. Talk is cheap, actions speak louder than words.
