Boaz Beard was the next wrestler to do this after Romero Cotton. Beard won at 152, 160, 171, and 189. Even more impressive is that Boaz was 40-0 as a freshman.
I believe Goddard only wrestled 321A opponents up until regionals that year.

JK! That is REALLY impressive. What weights did Caldwell wrestle? I believe he might have made the biggest jump from Freshman to Senior year of any of the 4xers.
