The Valencia Flyers. Of the Western States Hockey League!
Mats Zuccarello has already had himself a pretty distinguished career for an undrafted player. He's already got 303 games played in the NHL; he's got 203 points to go with them. He's a half a point per game player in the playoffs. He'll be 29 to start next season, but he only just got his NHL career started when he was 23, only playing in New York.
Enter: his younger brother, Fabian. Fabian Zuccarello is also undrafted. Like Mats, he's a relatively small guy: 5'10 and 157 lbs.
