Liked Khudobin when he was with the Wild. He's got a pretty crazy style, kinda like Tim Thomas and like Thomas, he's a pretty small guy too. Don't think he's quite starter material but I can see him being a solid back-up now that he's finally getting his chance.
Not sure if Kuemper will ever be a starter or not. If he does become a starter it's likely going to be with a different team as the Wild have Hackett and Gustafsson ahead of him on the depth charts.
Svedberg's a never-give-up scrambly type of goalie, makes him look awkward at times. He also has some temper. But when he's hot, he's really hot. Really only needs to become more consistent, work on his rebounds. Looks like he's made a really smooth transition to NA, which is somewhat surprising to me.
Nilstorp is a stay in the crease guy, extremely economical. Consistent, calm. He needs to become much better at swallowing the puck, which was evident in the first NHL game last night. His work going forward will be learning to be aggressive at the right times, NHL shooters will beat you otherwise. He's a latebloomer, but see no real reason why he couldn't be successful.
Both have starter potential, but maybe more in the mid-low tiers.
