I'd do it as fast as possible so Atlanta doesn't have time to reconsider... Defensive guards with no offense are the least valuable commodity in the current NBA and can be drafted every single year.
Name 5 better defensive guards than Smart in the past 5 years.
I'll wait.
Show me proof their better, and I'll give you 5 TP's.
Chris Paul
Patrick Beverly
Andrew Harrison
Kyle Anderson
Jonathon Simmons
Tony Allen
DeAndre Liggins
Rodney Hood
All guards with higher Defensive Real Plus minus than Marcus Smart.
http://www.espn.com/nba/statistics/rpm/_/sort/DRPM/position/2Smart is considered a point guard by espn so if you click on the link just click the hyperlink to pointguards and you'll see his DRPM is 0.76 (which is very good for a pointguard)
Here's how ESPN explains Real Plus Minus, Offensive Real Plus Minus, and Defensive Real Plus Minus
"Where does real plus-minus come from?
Drawing on advanced statistical modeling techniques (and the analytical wizardry of RPM developer Jeremias Engelmann, formerly of the Phoenix Suns), the metric isolates the unique plus-minus impact of each NBA player by adjusting for the effects of each teammate and opposing player.
The RPM model sifts through more than 230,000 possessions each NBA season to tease apart the "real" plus-minus effects attributable to each player, employing techniques similar to those used by scientific researchers when they need to model the effects of numerous variables at the same time.
RPM estimates how many points each player adds or subtracts, on average, to his team's net scoring margin for each 100 possessions played. The RPM model also yields separate ratings for the player's impact on both ends of the court: offensive RPM (ORPM) and defensive RPM (DRPM)."
By the way I think Marcus Smart is a very good defensive guard, he's just not a great overall guard. He's ranked 156 currently out of active players in real plus minus.
