Babcock was on a 78 point pace, and even in the most cherry picked time-frame you could find for Keefe, he was still at an 85 point pace, even with horrible goaltending and constant injuries, especially to his defense. Most of the underlying metrics maintained fairly well through all of Keefe.
Markstrom had a better year this past year, but when looking at a bigger sample, I'm not sure you can say Markstrom is an upgrade. We don't know if he wanted to come here, and it took a 6m x 6 year investment to get him anyway, which means losing something else off the roster.
Not sure which goalies under contract you mean. I guess Kuemper was kind of thrown around, but again debatable on if he's an upgrade, and the price was reportedly quite high.
Again, you said you like Andersen, so not sure what the issue is. Good job by Dubas for keeping him, right?
