Too early to tell, but looks promising
Horak still looks like an interesting player, although I think Brossoit is clearly the player that the Oilers were more keenly after in the deal. At the time of the deal, MacTavish was Hell bent on shoring up the club's goaltending depth in the system. Since the deal, I'm fairly convinced that Brossoit is on the right trajectory. He turned his game around after becoming Oiler's property, and hasn't looked back at all. As for Smid, I always liked him, particular his character, but you can't look back with young players like Klefbom and Marincin in the mix and Nurse in the wings. Marincin already looks better than Smid, and Klefbom is showing signs of surpassing Marincin. There simply wasn't room to keep Smid at his salary.
Brossoit is looking like a great prospect and has helped to elevate Bunz's game--according to Bunz--since his arrival, which adds some collateral goodness as well. I hope that they wind up in the AHL together next season at some point. Could be a solid tandem. Bunz remains a player that I still have reasonable hopes for, but what I like most about Brossoit is that he performs so well under pressure; it makes me think that he can become an NHL starter. He competes hard, and as the stakes go up, he gets even better. Olivier Roy, who went the other way in the deal, seemed to collapse under pressure (at least that's my impression after the WJ tournament). While most of the technical stuff is teachable, a lack of mental toughness in big games is harder to teach to a goaltender.
I think that this deal is hard to get a real read on yet, and could still turn south. I think that this deal is still very much a "wait for it" one. I think that we'll be very happy with Brossoit in years to come, and Horak could still be a player as well.
