Thomas took it upon himself to push the Celtics past a 17-point second-half deficit and into overtime for a 112-109 victory over the Memphis Grizzlies on Tuesday night.
Thomas scored a career-high 44 points, including 36 after halftime. He also matched his career best for 3-pointers, going 7 of 10 from outside the arc.
"I just told myself to be a little more aggressive and look for my shot a little more," Thomas said, later adding: "I wasn't trying to get 40, but I knew I needed to be more aggressive."
After the Grizzlies took a 106-105 lead on a rebound basket by Tony Allen with 1:10 left in the extra period, Boston scored the next five points.
Memphis coasted to a 45-31 lead in the first half. Then the Grizzlies looked as though they were coasting through the second half -- and not in a good way.
"Basically, we stayed in the locker room at halftime," coach David Fizdale said.
Both teams had last-second opportunities to win in regulation. Gasol's turnaround 8-footer with 2 seconds left in regulation bounced off the rim. With less than a second left, Horford failed to convert an inbounds pass at the rim, sending the game to overtime at 97-all.
"Coach (Brad Stevens) told us at halftime, `Just stay with it. Stay composed," Horford said. "We had an awful first half, and he just said, `If you guys stay with it, I guarantee you that you'll get hot, you'll get to scoring.'
"We believed, and we kept playing."

YOUNG AND OLD
Stevens, at 40, is one of the youngest coaches in the NBA. Meanwhile, on the other sideline, Vince Carter, at 39-plus the oldest active player in the league, came off the bench to play for the Grizzlies. Carter is about 3 months younger than Stevens.
Thomas said he got some motivation from assistant coach Jerome Allen at halftime. "He said, `We need 40 out of you to win," Thomas said, adding that Allen told the guard he wasn't built to score 40 points. "We were joking around, but I was like, `I got you.' He was just playing with my head a little bit."
