To your question, if Murray starts and win's the Finals as the Pens starting GK. Then yes absolutely. I think so
Fleury carries a $5.75-million cap hit for three more seasons after this one.

Teams will only be allowed to protect one goalie in an expansion draft apparently, meaning Pittsburgh will lose one of Fleury or Murray. But they could threaten Fluery to waive his no trade clause if I'm correct.
But having two great goalies is a pretty good problem honestly. Fluery is still a pretty decent goalie at 31. There are teams dying to just get one of them.
