If you're Jaylen Brown and you shoot 7-23 in a game, any finger you're pointing should be aimed at yourself, regardless of what else happened or didn't happen.
IMO, what happened in the final 4 minutes and OT is secondary. We had a 21 pt lead with 4 minutes to go in the 3rd quarter, and 12 minutes of game time later it was tied. You can't have stretches like that, and you can't have Brown & Kemba shooting 12-44 against anyone, or we're going to lose no matter the opponent.
As a team, CBS and the Celtics have to figure out what the offense is going to be when opponents lock down on Tatum.
