The Celtics played 19 games (23.1 % of their schedule) in 32 days. That's an average of 4 games every 6 days.
The Celtics play their final 63 games over 137 days. Thats an average of 4 games every 10 days or so.
I expect this team to be more prepared with practices between games and a better ability for game planning by the coaching staff with the spread out schedule, meaning, probably more wins against good teams and blow outs of bad teams
