The NBA has released schedules for the Western Conference semifinals, even though we only know two of the four teams that will participate. Each series features a back-to-back. The Spurs vs. Clippers/Grizzlies series will have Games 3 and 4 on Saturday and Sunday.
Spurs coach Gregg Popovich has consistently sat old men Tim Duncan and Manu Ginobili on the second night of back-to-backs this season. Ergo, it's totally possible that Pop will effectively tank a real life playoff game to rest his stars for the rest of the series, the conference finals and the NBA Finals.
