At this point you have McKenna who isn't even Flames property but who has a chance at putting it all together (for the Flames or another team), Philp who dominated USports (is he Derek Ryan, Joel Ward, or countless players never heard from again), Valiev who is a solid but unexciting defenceman, Schneider who is unpredictable simply by being a goaltender, and then a bin of players with 0% chance of ever playing regularly in the NHL.
Jeremy McKenna
Whether he should be on the list is debatable, but I'm voting based on the players that appear on the list.
One dimensional goal scorer but scoring goals is the most difficult skill in hockey. Excellent at getting open and finding gaps in coverage which allows him to get his hard and accurate shot off. Also terrific on the powerplay. But, his defensive shortcomings significantly reduce his probability of success. Hockey is full of junior snipers who didn't pan out, but there are a few who have turned into mighty good scorers. Over 5 shots per game is insane.
