Luke Kornet made his return to TD Garden with a beanie on alongside a nondescript long-sleeve shirt and jeans. He sat in the second row behind the basket after sneaking in several minutes into the Celtics-Raptors game earlier this month. During timeouts, he greeted former teammates and eventually moved up to row one at the behest of Wyc Grousbeck. That, as much as the eight points and eight rebounds he provided in his on-court appearance the following night, reflected the Kornet experience in Boston.
