That's a fair point, the nature of the Solis win made it hard to value, Briggs may well be a better opponent than Barrett, however I think an overwhelming stoppage of barrett is better than a points win against Briggs.
Well, obviously. Povetkin's victories over Byrd, Chambers, Chagaev Boswell, and Huck, also put Vitali's Position as number 2 under threat.
