The Bucks are good at never losing, for some of these reasons.
1. The defense is the best in franchise history, so far.
In the span of two seasons, from 2007–08 to 2009–10, the Bucks had transformed from the very worst defense in the league to the best in the NBA. The personnel had changed a lot, with guys like Mo Williams, Charlie Villanueva, and Bobby Simmons discarded for the likes of Luke Ridnour, Kurt Thomas, and Luc Mbah a Moute. But they also had in place a new defensive system, and renewed priority on that side of the ball, with Scott Skiles on the sidelines maximizing everyone.
