I won't fault the first two Wild goals on Kuemper(both goals a Wild player was left completely unmarked), but goals 3, 4, and 5, he's very capable of stopping those shots. Kuemper has a weak glove, but what exactly is Scott Murray working with Kuemper to improve it?! I use to do some simple techniques with tennis/squash balls off the wall, catching bare-handed and with the glove both in goalie stance and in the butterfly. In practice I would catch glove side shots without turning my head(can quicken glove response a bit). I would also have Kuemper play a bit more upright in certain situations...
I have become more and more disappointed in Kuemper overall play in net, as he's showing signs of being a Holtby 2.0! Won the Cup and then fell off a cliff each following season.
