Prospects are essentially a betting game. You never know what will happen to an undrafted player that will turn them into an NHL all-star, or which lottery picks will never make the NHL to start with. There are certainly some guys that are just constantly overlooked, but you can just feel in your bones that they'll turn out to be spectacular. Who are these players, and why do you think they're going to turn heads in a few years? I'll start this off by rolling with Nick Mattson. He's never really impressed anyone at big prospect showings, but he won USHL Defenseman of the Year this year, and is headed to play for the Fighting Sioux next season to refine his game. UND, with its great hockey program and having just lost three of their premier dmen, will be exactly what Mattson needs to take his game from great amateur to great pro.
