Brad Stevens found success last year in smaller lineups. The first unit struggled to score at times, but a second unit led by Isaiah Thomas handling the ball, Jae Crowder at the 4, and Jonas Jerebko sliding to the 5 gave the Celtics an advantage. During the team's late season 24-12 push to the playoffs, lineups featuring Thomas, Crowder, and Jerebko were a stout +91. That's 27 points better than the next most effective trio (Thomas, Jerebko, and Smart at +64). Granted, the IT, Crowder, Jerebko threesome saw most of their time together against second units, but their impact was undeniable.
