But a rebounder was needed. Inexplicably, Popovich apparently forgot that the defensive possession doesn't end until the defenders secure the ball.
Personally, I just hate the strategy of making yourself small (relative to the offense) to guard the perimeter, especially, in the case of last night, considering the size of the Heat's lineup and shooters. Over my years of playing and watching BB, I've seen that strategy fail so many times it just boggles my mind that coaches do it.
Also, Bosh was still in the game. So it wasn't like Duncan would have had to guard Allen or another shooting guard.
