Quote from this website:http://www.teamhayes.net/MCD_ALLAMERICAN/aahsb01.htm
Looking for a barometer to determine the chances of a college basketball team winning the NCAA Championship? At least one McDonald’s All American boy had been part of every title since 1979 until 2002 when the University of Maryland won the title without any former McDonald’s All Americans. In 2003, the streak began again with a victory by Syracuse University. In all, 76 alumni have played a role in at least one NCAA title.
The site only goes up to 2005 for championships, I didn't even bother to look but I would be surprised if a team after that managed to win without a McD's All American(pretty sure Maryland is still the only school).
So come on Painter! Land us that coveted blue chip!
