Former Orlando Magic center Pat Burke played nine years, making stops in Greece, Spain, Russia and Poland.

Burke says players such as Deron Williams are in for eye-opening experiences.

"You have to live it to understand it," he said.

Pat lived it, often loved it and often loathed it.

"I saw a lot of NBA guys come and go. It's their attitude. That was the biggest thing," he said.

"Any guys going overseas have to really adjust their thinking. It's one of the biggest sacrifices you'll ever make.”

Along with the culture shock and inconveniences facing players, Burke says NBA players must change their style of play. "No fade-away jumpers, no running down shooting 3s. You have to work for shots," he said. "NBA guys who didn't like that were on the next flight out."
