Just rewatched the the stretch in the 4th from where Brown got caught in the air and turned it over. Celts were down 3 with ball. Golden State scores in transition off the turnover to go back up 5. Could be a crusher. Golden State proceeds to score on 5 (or was it 6?) straight possessions, but actually sees their lead dissipate, as the Celtics are one upping their 2-pointers with 3-pointers. Just incredible shooting and mental toughness.
Loved the moment where play was going on while they were playing Steve Kerr pumping up the Warriors during a timeout after the Celts when up by 3 (around the 5 minute mark): "We gotta play with more force. They're hitting all sorts of shots. We're at home. Only down 3. Just gotta grab the momentum." As they're playing this, Celts force a turnover, and Horford goes down and swishes another 3 to go up 6. Warriors never recovered.
