Ok, game 3 was played with an injured Parker. And Ginobili was off, as well.
If it were Doc, he would not have been able to make the adjustments, take LBJ out of his game, while spreading the offense around to other players. Instead, he'll try to get Manu to run isos, as a way of compensating for Parker not being JoJo of the night.
I predict that the Spurs will lose, 4-2 or 4-3, if Parker's not back however, they'll give it a good fight till it's over.
In contrast, I think Doc would lose the series, 4-1 or 4-2, even with a healthy roster.
