Probably Marco Antonio Barrera - past his prime for sure, but still solid at that stage - or Juan Diaz... Diaz lost some of his shine after losing to Nate Campbell, but He came back with great performance against Katsidis and I think He was as good as ever in that first fight with Marquez. I think Gainer was a bit underrated win also. That would be my "honorable mention".
Barrera. He was on a great run and was the lineal guy at 130. Diaz was a good one too. 10 years younger, bigger and stronger and in his hometown. Casamayor was good too. Privileged to have attended all of these.
