This nonsense targeting of Marcus Smart for criticism needs to stop.
His performances are being detrimentally affected by CBS's terrible lineup decisions that are regularly putting Smart in positions to fail. It is not Smart's fault that his coach is doing this. It is CBS's fault.
If you do not like Smart's performances, blame CBS. Not Smart. You are targeting the wrong guy.
Let Smart play in a lineup with proper spacing, proper ball-handling and proper passing and watch him return to the player we know and love.
Keep Smart in lineups where there is deficient spacing, deficient ball-handling and deficient passing and expect to see more of the same. Playing Smart in lineups where he is clearly the 3rd best offensive player on the court (ahead of Theis & T.Thompson) and forced to make more offensive actions on the floor due to both (a) the limitations of Theis & T.Thompson (b) defenses hounding Jaylen and Tatum and forcing someone else to beat him ... is a recipe for disaster.
This is what CBS is doing. Smart's downturn in performance levels is a result of this. Blame CBS. Not Smart.
That shot on the last possession is on Smart, not Stevens. Brown was open and available for a pass on the right wing. He was being defended by Tyler Herro, the worst perimeter defender on the Heat and one of the worst in the league. He would have produced a much better shot. He also could have figured out a way to get it back to Tatum. A Tatum 35 footer with Butler defending is probably a higher percentage shot than what Smart did (probably both around 25%).
If I'm an opposing team or coach, I would send Smart's man to double team every time, and then recover with a rotation when Smart gets the ball and drive him off the three point line. A Marcus Smart drive is one of the lowest percentage shots of any starting player in the NBA (outside of a contested three from a non-shooter or something like that).
You could argue that CBS maybe should bench Smart in late-game situations if he insists on offensive possessions like that, but frankly, that's a no-win situation for CBS. I think if you have Smart on this team with this bench, you have to play Smart.
