IMO Pastner did some things very well this year, especially pertaining to keeping things together after the rough start without Jose, and with getting the team to finish games in the back half of conference play.
That being said, I don't see this year as a CoY level year. In year 1 I thought he got pretty close to the max he could in terms of wins out of that team (in conference mind you). This year I don't think that's the case. I think this team could have competed for the 4th spot, and while we could finish 5th, there is a big divide between 4th and 5th this year. That doesn't mean that I think he did a bad job. I think he did a lot to give us reasons to be optimistic going forward and reasons to believe he could be a long term solution for us (could be mind you). But I don't see CoY levels.
That being said I think the coach who did the best this year was Bennett. Given what they lost to even have a chance at finishing 1st (tied for) with 1 game left is pretty remarkable. I don't think he'll win it just because he's won it 4 of the last 6 years but man I don't think you can convince me anyone in the ACC did better than him, especially with how they have been playing later in the year.
