Don't go hating on the NCAA. A lot of the team's most valuable players have college hockey experience. O'Connor would be a great addition to the team's already stable goaltending prospect pool of Bibeau and Sparks. One of the greatest goaltenders in Leafs recent history, Eddie the Eagle Belfour, was also signed as an undrafted free agent out of college. Was that a long time ago? Sure. But there's no reason to not look at college hockey for great prospects.
And if you want to look at Europe, Artemi Panarin is tearing it up in the KHL and no NHL team has his rights. Shanahan and co. would be wise to look at him as an option for the Marlies, and hopefully for the big club.
And then the team should draft me while they're at it too. I have significant beer league experience that will totally translate over to the NHL.
