How big a difference does Anderson Varejao make on the defensive end of the floor for the Cavaliers?

Here's a snapshot from the Cavs' 90-89 loss to the Detroit Pistons in an exhibition game on Tuesday night at The Q:

With the forward/center in the lineup, the Cavs held the Pistons to 33.3 percent shooting in the third quarter while building a 12-point lead. With him on the bench, the Cavs gave up a 10-0 run in the fourth quarter as the Pistons got back into the game, eventually winning on Austin Daye's two free throws with 3.1 seconds left.

Basically, the same thing happened on Friday night in Detroit, although the Cavs were able to survive that drought. That wasn't the case Tuesday, as the Cavs finish the preseason 1-1.
