I like Starr's ideas behind Spinks. I'm not sold that Spinks would win though. I could see him making it close but PBF getting the vegas decision in an all together boring fight. I'm not sure Casamoyer could beat PBF but I think it would be a very competitive fight. To beat PBF the fighter needs to be a Tommy hearns type fighter. Tall rangy with the ability to fight inside and out and would need to be able to seriously bang. No one is going to take Floyd out early. Its going to take 10-12 rounds of constant stalking and pressure.
