Lewan was 4-2 in his 6 OT matches, the same winning % as Morningstar (6-3). But with 9 OT matches Morningstar is the King of the "But, Wait. There Is More" Hill.
But the real King of the Deep Water was Illinois' John Lockhart. Across the 2001 and 2002 tournaments he went to OT 7 times and he got his hand raised 7 times.
