Okay - that's a completely defensible decision to not call the timeout there by Joe. Tatum was cooking and scorching hot, and he got an excellent shot. That's a perfectly fine decsiion in that situation that a timeout wouldn't have helped in.
It's still frustrating that we only decide to play and actually attack the basket the last few minutes of the game. This is the problem with the philosophy that prioritizes so many three point jumpshots. You get lazy, and you'll go through spells where you can't hit anything. At least going to the hole more it's a higher percentage and you can draw contact to get to the line.
