Malcolm Brogdon was just about everything the Celtics could have hoped when Brad Stevens traded for him last offseason. He accepted a role off the bench and excelled in that role to the point of winning 6th Man of the Year. He was 2nd on the team in 3 point shooting at 44.4% (just behind Elite Shooter Al) in the regular season and flirted with another 50%-40%-90% year. He even gave the team another ball handler that could get his shot off when the offense broke down in the playoffs.
So why does it make sense to trade him?
