Rookie defenseman Mathew Dumba has been impressive at camp thus far. Dumba has had a tough time in junior hockey this season after being drafted seventh overall in the 2012 draft as his play was spotty and he failed to make the Canadian World Junior team. But he has put it all behind him and has impressed the Wild coach Mike Yeo. "I'm really happy with what I've seen from him," Yeo said. "He is going to be a really, really good player. It's a big jump; one week you're playing junior hockey, and the next week you're coming out and playing against world-class players." Don't expect him to stick although the Wild could give him a five game trial to acclimate him to the NHL lifestyle.
