Good time out by Brad.
Was it though?
See, this is my problem when people complain about timeouts Brad doesn't make when fans want him to. It assumes good things happening after the timeout.
After this "good" timeout, Indy continued on their run and closed the game down to 4 points. The timeout didn't stop Indy's momentum.
What did change the momentum was the Celtics fighting through, getting stops and making shots so the C's opened things back up to 9 to end the quarter.
The assumption of good things happening after timeouts is poor and not based in any logic.
