...we asked seven NHL.com writers which goalie signing will have the most impact on the 2020-21 season. Here are their thoughts:
Thomas Greiss, Detroit Red Wings
The default answer to this roundtable should be Khudobin, but since he didn't change teams, I'm going to go with Greiss. You can argue that there are flaws in just about every goalie who has changed teams, from evidence of decline or inconsistency in their game, but in my opinion, the two who rise slightly above the field are Markstrom and Greiss. The Red Wings were the team that needed an upgrade at goalie the most after allowing a League-worst 265 goals last season (.
