Well they drafted Portillo in 2019 and traded for Levi in 2021, essentially drafting a goalie every other year, and Portillo is probably gone. Personally I think was scared-off by Levi. So taking a goalie that often might work against you.
I was working with a guy who is an Islanders fan. You think the angst over TNT was bad (prior to the last few games), imagine what they're saying about Barzal and his $9M/year deal.
It took Petersen 6 seasons to get to the NHL and then he was sent back down the next season. He's currently given up 9 goals in 2 games. I don't view him as much of a loss.
