I really love Marcus, his defense, and toughness is something we need, his ability to make special plays is uncanny but...
Smart needs to be a facilitator, and not anything close to a primary option on offense.
Shooting percentage is a very important stat, that he needs to pay attention to. The shots he misses, are shots other more accomplished scoring options could take advantage of. That's how you win CONSISTENTLY.
No way, will I say trade Marcus...when you have a player with his ability to create intangibles you hold on to him, and develop him further. He's 22 years old.
If you're on the "trade Marcus" band wagon, check out all past World Champions all having one or several of Marcus Smart type of player on the roster. Its simple...You don't win in the NBA without this type of warrior on your team.
