Tatum would have been in sooner had there been a stoppage sooner. He came out with 5:28 to go and the Celtics down 24-7. At 3:01 Brown was fouled on a 3 point attempt and the score 29-10. Brown hit all three, 29-13. Fifteen seconds later, Dedmon fouls Smart who hits 1-2, 29-14. Tatum could have come in on either foul. But from 2:42 to 0:14, Miami went on a 10-4 run and there were no stoppages. Of course Ime could have called time.Starting Theis set the tone for the first quarter which is where the game was lost. Dude was completely useless on both ends and generously helped get Bam off the mat. The error in starting Theis was compounded by subbing out Tatum for a long first-quarter stretch and putting in White when they desperately needed some scoring. Not Ime's finest performance tbh.
