Some days ago Smart got Giannis into foul trouble in a myriad of ways including lying down on the court and making Giannis trip over him more than once. The Celtics won that game and Smart, as always, played a role.
The guy is a magician and he's cheap.
He runs the defense when he's on the court and the Celtic's defense is usually toward the top of the league.
Auerbach rarely traded "defensive players" and trading "defense for offense" isn't worth it as offensive stars are overvalued and Marcus Smart in such a trade will be undervalued.
Tell another player to pack his bags...ok?
