Goaltending is perfectly fine.
I don't see how you can completely dismiss any and all concerns about the goaltending.
Binner at his best is a top 10 NHL goalie. When he's on, he's as good as anyone at getting square and making the first stop. He's very good against the rush, he's a great puckhandler and he battles well to overcome his below average lateral mobility. But he's struggled to be on his game as much as you need a 55+ start guy to be on his game. We got 'on his game' Binner in the playoffs, but he struggled for long stretches last season.
I'm not too low on Binner and have a decent degree of confidence in him. But he's coming off a season where he put up a .901 SV%, a -6.4 GSAA and only started 37 games because his partner won the net.
The new backup has been a good NHL goalie in the past, but he'll turn 37 mid-season and put up an .891 last season. Maybe you can chalk that up to playing behind a bad Wings team, but his partner was noticeably better (.901) and Greiss had a .912 the previous season behind that same team. He might be washed.
Every other goalie in the organization is 22 or younger. There is upside in that group, but none of them are ready for the NHL barring a massive leap forward this summer.
There are very real reasons for concern. I'm optimistic that it will be perfectly fine, but there are real red flags that shouldn't be ignored.
