Per Mr. Scott's site in 1952 Cliff Hagan was credited with 128 assists in 32 games, but at 6-4 he was more of a Forward/Center. For true bigs (6-9 and over), one could make the case Amari is the best passing big man in UK history. As the players play more together, the turnovers should lessen.
In 17 games so far Amari has 45 assists. And it should be remembered, Williams only plays 21 minutes a game.
