Your opinion of those prospects is not really relevant to the point I was making, which is that they are closer to making the NHL than Hickey and there is a limited number of spots (1 or 2) available for them next season as per Treliving himself.
Any Flames fan will tell you that Andersson and Kulak are by far the most likely D prospects to make the Flames next year, with Kylington at 3. If Hickey had signed with the Flames this summer and exceeded expectations in Stockton, he might have displaced Wotherspoon on the depth chart and/or competed with Kylington if Kylington stagnated, but he wouldn't have played in the NHL and Fox would have leapfrogged him the moment he turned pro. Your assertion that not being a better D prospect than Rasmus Andersson means Hickey should go play in Europe doesn't change the fact he's not a better D prospect than Rasmus Andersson.
Opportunities to make the NHL were definitely scarce for Hickey in Calgary. You seem resolved to believe otherwise for some reason, but maybe you should defer to people with more knowledge of the situation in this case.
Ya that's pretty much the reality of it. Andersson and Kulak are a step above Hickey and Wotherspoon is on the same level and look how we treated him.
He was never going to get a fair shot in Calgary.
