The goalie crop in this year's NHL draft class is about average. The top tier is four deep for me, but I don't expect these will necessarily be the first four off the board, as there are NHL people who really like Evan Fitzpatrick and Joseph Woll, and there are reasonable arguments to get them into that top tier.
Carter Hart is a great goalie prospect. He's right there with the first goalies to go off the board in the past few drafts, and is better than some of them.
I expect the first goalie will go in the early to middle second round, and I'd have them placed late second-early third. I could see either of my top two as the first one off the board.
