His first year there are no expectations, especially if the Celtics go all in for a top pick in the draft next season. Even if they don't win the Wiggins sweepstakes, Julius Randle, Aaron Gordon, and Andrew Harrison are nice consolation prizes. This is nothing like the Tim Duncan draft where it was Duncan or bust. If he starts laying the foundation within the next two years and setting up a nice nucleus, unless he wins a championship, I see him getting Rick Carlisle'd in year three (replaced with a NBA experienced coach, in that case Larry Brown)
I'm a Celtics fan and I am kinda surprised George Karl wasn't the pick. The job he did with the Nuggets was remarkable and if the Celtics are looking to rebuild with young talent, Karl would have been the guy, even if he has a Larry Brown track record of alienating people.
