I'll rate it as B . . . he failed to outbox Mayo as expected and he tired out after the 7th round . . . I'm not too happy with that showing.
i'd say it was B, giving his last fight was at welter, moved up to 154, but was in the ring with a fighter a few pounds shy of the light heavyweight limit.... but i'll move it to a B + since he DID manage to KO him.....
I'll assume that if Mosley hadn't produced a thrilling knockout in the last 20 seconds he'd be getting worse grades. Imagine if he'd lost, which was apparently almost a possibility.
I give him a C-. Poor performance in my eyes except the 6th and the 12th. he just didn't throw any punches.
I will give him a D+ The two fighters who Shane will always be mentioned alongside DLH and Tito both delt with Mayorga relatively easily compared to Shane. Apart from the KO i thought the fight itself was awful to watch and at times Mosley looked like he didnt want to be there.
I gave him an A-... Mayorga came in at 170 lbs!!!! he was tired and still manage to pull out the KO at the last second of the final round... What else do you want to ask from the guy?
