Charlie Villanueva was a little embarrassed at the topic.

The subject was his free-throw shooting and how a guy with a career 78% shooting percentage can scuffle at a 32% clip.

Friday night, he had to suffer through the ignominy of Cavs coach Byron Scott going to the Hack-A-Charlie strategy in the fourth quarter of the Pistons' 117-99 victory.

Villanueva shot 3-for-8 to actually raise his free-throw average, but Villanueva just shook his head Saturday when asked about it.

"Wow, that's disrespectful by Byron Scott," Villanueva said jokingly. "By the numbers, good move.

"It's just one of those years where I can't make free throws. I haven't gotten (many) attempts. That was crazy, though. That was crazy how he pulled that card out."

Villanueva hinted at one of the issues -- the lack of attempts. He has just 25 attempts as the offense uses his outside shooting threat to create space in the paint for others. His three-point shooting percentage is almost seven points higher.
