Let's go through you majestic coaching, you sub in white you get the stop with 36 seconds, you call a timeout to bring in mills. (Your idea, not mine) So you have no timeouts and the ball with 36 seconds left
so you go 2 for 1 right, you make the basket yay you're tied you stop Denver with one second, no TO overtime. You don't stop Denver they're up and you don't have a timeout, you lose.
You don't go 2 for 1 run it to the end of shot clock, miss, game over. Run it to the end of the Clock make, Denver calls timeout, you don't get the stop,you have the ball with no TO assuming denver didn't take it all the way down anyway, you lose. You do get the stop, OT.
***caveat this is assuming the Spurs last make was not a three pointer, cause c'mon, they weren't making no damn three to win the game.
Now let's run another hypothetical scenario,
They get a stop they don't waste their Timeout. Then the initial scenario results in at least an attempt to win the game after advancing the ball, or a chance to tie the game with a stop and a miss.
I don't get you if Derozen doesn't miss that damn shot the Spurs would have at least had an attempt to tie the game in the end, which guess what even if they get the stop down 2 they still would have had to put it in the basket. The game was lost when he missed that shot, not when murray made his 2.
