The Boston Celtics have been booted from the NBA's inaugural in-season tournament by the Indiana Pacers after a performance that was all too familiar for some. Fans have seen hungrier teams outwork the Celtics on nights when the 3-ball isn't falling. But there was more to the loss than those familiar flops from the past, and not all of it was bad. What can the Celtics take away from the IST loss, and how can Boston get better moving forward? Are there players or lineups we would like to see more of? And if the current supporting cast isn't quite enough, who might make sense for the Celtics to make some calls about with many players around the league becoming moveable after Dec. 15?The hosts of the CLNS Media "Celtics Lab" podcast put on their thinking caps after the loss to focus on what's next for Boston, how they might make that happen, and even debate whether Jayson Tatum deserved his Player of the Month nod, so strap in and join us for a bumpier ride than usual.The Celtics Lab podcast is brought to you by FanDuel.Learn more about your ad choices.
