I'm with Bowiac on Bradley, I'm really surprised with the love he is getting. I look at him, and the rest of our back-court for that matter, through a different lens. Instead of looking at what they are doing, I think about what they would be doing with a lesser coach because I think Steven's amazing coaching is what makes it work and we are quickly taking that for granted.
In the backcourt, Stevens has to start the game with a significantly undersized Thomas alongside an undersized, for the 2 anyway, Bradley. Its one thing to go small, but its another thing to have players who are small on the court, and I'm convinced that being forced to play Bradley, Turner and Smart for big minutes would cripple most teams because Stevens covers up so many of the warts/untraditional nature of these guys. If we look at the bigs on the team, the biggest holes that I see are that we have Amir Johnson and Sully starting and whichever of those guys we think of as the C is very undersized. Kelly rolls in off the bench, and sure he has some warts, but as a 6th man thats a great role for him.
If we move Bradley in the deal for Horford, we gain a traditional C who probably allows Amir to play at his more natural 4 position, and I think takes minutes away from Sully. It creates a hole at SG, but I'd argue its easier to find a SG than a C, and really any backcourt position is easier to fill than a front court one. If Kelly is moved in that deal, his TS% of 56% (compared to a league average of 54%) is probably replaced by Sully's 47% and I think Sully is really more offensively skilled than defensively so those numbers are really brutal to look at.
Now, with all these holes I just pointed at on the roster, Stevens has them on pace for 48 wins which seems a big unlucky considered the expected pythag expects them to have 52 wins at season's end. Which is why I'd really suggest we be a little more critical of what these guys are doing here.
