I've watched him play about 25 games this year and I don't really see how you come to that opinion. I think the worst game I seen him play was his first game back in Calgary after being returned from Flyers' camp. Other than that game I can't think of a game where he was flat out awful. He had a stretch a couple weeks ago where he wasn't putting up points, but I never considered his play inconsistent or of the undraftable quality. Even when Sanheim has an off game, he generally makes an impact in at least one end of the rink. He's big, mobile, great hands, great passer, can PK, QB a PP, can play the left side, the right side, offensive or shutdown role. He never gets beat one-on-one. He's definitely an underdog to be a top 6 guy, but he would be a good candidate as a 7th guy because you can plug him in to almost any role.
I know you're going to say I'm biased, but I would argue Sanheim is more consistent game-to-game than Morin. He's playing his best hockey of the season right now. I don't want to make him out to be a prospect with zero flaws because he certainly has his faults, but I think people look at the year he had last year and just associate words like raw and inconsistent with him when I just don't think that's true. Again I think that would describe Morin more so than Sanheim.
I did hear an interview with Jankowsi talking about Hicketts and I think Jankowski had to change his shorts after he got off the air. He may have an inside track to a spot on the right side.
