It's never easy to tell what Andrea Bargnani is thinking, or if he's thinking at all.

Celtic Kevin Garnett tried to get a rise out of him midway through Sunday's pre-season debut by stretching out his arms and clapping his hands three times, hard, a couple of inches from Bargnani's nose.

The Italian's permanently slack expression was not altered one iota.

Later, Bargnani would say that he didn't notice Garnett riding him all game long. In this rare case, you half-believe it's true. Bargnani floats through games the way he appears to float through life — gliding along just above it all.
