I think you still have to include Byrd, Bouzakis and Frost in this group, considering Knox has lost to both Bouzakis and Frost. Frost’s only losses are to Ayala and Romney. Byrd beat Bouzakis and only loss is to Ayala. Bouzakis has 3 losses to the field (+1 to Davino) but they are to Romney, Byrd and Shawver. But I probably draw the line before Shawver who has worse losses
