I just hope people would give at least 5-10 games before declaring him a bust. It does amaze me a bit that no-one seems to remember that as long as he got frequent ice time last year there was absolutely no problem. And he wasn't the worst player in the preseason either and after having two good games I'm sure he would've started the season in most NHL teams.
However, it seems to me the Oilers have made several questionable moves with him, and to be honest I'm not sure if this is the best place for his development. I hope no-ones feels insulted by me saying this, I respect Oilers and its fans a lot, but this isn't the strongest asset you have IMO.
By the way, since 2010 out of the players the Oilers have drafted at 2nd and 3rd rounds Slepy and Khaira are the only ones with at least five games in the NHL. I don't know if it's more about bad drafting or unsuccesful player development, but to me that looks worrying. I'm convinced Jesse's trading value is still very high, so that might not be such a terrible idea after all.
