Thomas says he was touched by the tribute to his late mother, Mary Thomas.
The former basketball standout says his mother taught him an important life lesson.
"If you can help someone else, help them," Thomas said. "And that's what's it's really all about. It's about loving, forgiving, being kind, and helping other people."
Thomas was joined by some of his eight siblings.
The dedication was one of several events Thomas took part in this weekend in city's West Side.
