08:58 AM ET 06.18 | What many people -- in particular, the Miami Heat -- don't know is just how lousy Dirk Nowitzki felt when he was on the court but unable to play with any gusto during Game 4 of the Finals. "He was the best decoy in NBA Finals history," says Holger Geschwindner, Nowitzki's mentor for the last 16 years. "He couldn't even walk around for very long. When he tried to drive, he died on the first step." That's the way it is when you have a sinus infection and fever well over 100 degrees, and you don't feel like doing anything, much less trying to go to work when your job is to physically outperform younger, stronger, healthier specimens.
