I am confused by this. Levi Haines has been in 5 OT matches in two years (11%), all against guys with winning records (Lewan twice, Robb, Zerban, Saldate) who make the tournament. And if he never wrestled Lewan it would drop to 7%.
Meanwhile, Lewan has had 16 OT matches in the past two years (31%), including one against someone with a losing record. And without Haines it would be 28.5%.
There is a significant style difference between these two wrestlers and going to OT is obviously driven by Lewan's style.
