THWC: National Treasures 2023 with Basketball Card Guy

<p> Always smiling- and always working...but somehow finding a way to add sick Basketball cards to the PC. Its Jon the Basketball Card Guy to talk about his experience at the National. He was the man behind the scenes for several businesses- walked the show- pulled off a flawless trade night and still found time for his kids! What can&#39;t this guy do? </p>
