My guess, which is an easy one, is Mumaw. Mumaw won the championship at this weight last year with 4A being by far the toughest. I say this because most of the top 10 kids in the state were in 4A. Benny Armstrong being no. 2 and Ethan Mumaw being no. 3 in the all around rankings. Mumaw beat Benny Armstrong 5 to 3 in the championship round, and beat everyone else in the state bracket decisively.
Mumaw went undefeated, with over 30 pins. I don't know for sure, but I don't think he had much more than 10 or 15 points scored against him for the year.
Many people overlook him because he never wrestles outside of highschool, so therefore you don't see his name posted everwhere like you do with other kids that wrestle national tourneys all the time,(which is too bad).
By the way, Ethan's hands are fine, no injury.
