He didn't make the playoffs last year but before that he made the playoffs six years in a row while being one of the best two players on his team.
The fascination is with his athleticism when he is playing the four. He creates turnovers, rebounds and creates scoring opportunities by flying down the court. He is also an underrated passer.
I would trade for him if the pistons would take on Wallace and a pick.
Josh Smith was generally not one of the two most productive players on the Hawks when they made the playoffs. Well, unless you use PER to rank players, but that would be stupid.
For the Pistons to take on Wallace for Smith, you'd probably have to give them a young PF and multiple unprotected firsts.
Smith was absolutely one of the two most productive players on the Hawks. He was also without question their best defender. It isn't close on that end of the floor. Take 09/10 season, which was the 2nd of 3 straight 2nd round teams. Smith was the Hawks leader in blocks and steals, 3rd leading scorer, 2nd leading rebounder, 2nd leading assist man, and 2nd in FG% on the team. 2nd in Win Shares, but significant leader in Defensive win shares. leader in PER. I'd probably call him their most productive player that year. It was fairly similar the year before and the year after that (you know when the Hawks were 2nd round playoff teams).
His problem in Detroit is he is playing the 3 and he is not a good enough outside shooter to be playing the 3 on offense. He was at his best when he was the 4 along side Horford and M. Williams. You put Smith in that type of situation he would be pretty darn good again. Boston is not that situation though as it has two young PF's in Sullinger and Olynyk.
Now if Boston could acquire Monroe and Smith, I would be ok with that.
Green, Sullinger, Wallace, Bass, 2015 LA pick, 2016 Bos 1st (lottery protected)
for
Monroe, Smith
I think that would be a pretty solid trade for both teams.
Boston's 15 man team would then be
Rondo/Smart/Pressey
Bradley/Smart/Young/Babb or Bogans
Turner/Thornton/Young/Johnson
Smith/Olynyk
Monroe/Zeller/Faverani/Anthony
I like that team. I think it could be pretty solid this year (45-50 wins) and still is young enough with enough assets to add to the team in the future. A real step in the right direction.
