I mentioned it in the trade thread, but I think he is a really good prospect. He seems to make a lot of his own chances. I am far from an expert, but just based on following him since the Flames traded for him, it sounds like most people see him as a middle 6 NHL forward one day, but with a high likelihood of making it at least.
I think Flames fans downplayed him because he wasn't our own pick and not an elite prospect. Treliving and Conroy both love the guy and I don't think it was easy for them to trade him.
