Warriordad,
To answer the question, the OW was voted on by all the coaches at the tournament, not just the host league schools and it probably had something to do with the level of competition at the particular weights. While taking nothing away from Wrestler B who in his own right is an outstanding wrestler, the 2 pins and 2 major decisions over the ranked wrestlers in Wrestler A's bracket probably helped the coaches make the decision.
I like alot of coaches have a hard time with these types of things, it's hard to vote for, and in the end someone is left out. In many cases, I wish we didn't have to vote for it, but it is tradition and you know how messing with that goes right.
Good luck to you and Wrestler B as well as all the wrestlers that compete this weekend.
