A ho-hum eight points, one rebound, and one assist is what you’ll see in the box score for Marcus Smart. It was twenty-eight minutes of statistical meh, but when Danny Ainge and the Celtics signed him to a 4-year, $52M contract last summer, they knew what they were paying for were his intangibles. It’s partly why he’s been inserted into the starting lineup and completely why he’s one of the most important voices in the locker room. Before any of these team meetings and before Kyrie Irving became such a vocal leader, it was Smart leading the charge.
