Grant Hill's father, Calvin, was a football star at Yale.
But the CBS/Turner analyst said before Harvard beat Yale in an Ivy League men's basketball playoff that he suspected Calvin was rooting for a former Dukie and current Harvard coach over his alma mater.
"He's a big-time Tommy Amaker fan," Grant Hill said. "I think secretly he does [want Harvard to win]. But he won't admit it."See alsoWest Regional bracket
Harvard did win Saturday, advancing to its fourth NCAA Tournament in a row.
Grant Hill recalled visiting Amaker when he first was hired (in 2007) and him talking about the power of the Harvard brand and of his vision for the program, which at the time included someday winning a national championship.
"I thought he was crazy," Hill said. "But to see what he's done in a short period of time - made Harvard relevant, won, been able to recruit good players - is amazing.
"Duke is a great school, but there's something about Harvard that differentiates you from everyone else. To have the opportunity to go to Harvard and play in a good basketball program and have a chance to play in the NCAA basketball tournament is something.
"Yale and Harvard weren't good when I was coming out [in 1990]. If it was now, I don't know if I would go there, but I would look at it. That would be something that you have to consider."
