I thought that Diaz was robbed in the fight with Guida, but he definitely was outworked with Stevenson.
The Maynard/Guida fights both could have gone either way depending on how you scored them. The Stevenson fight Joe won 2 rounds to 1 but round 3 was all Diaz and the fight was competitive the whole way through. I think Nate is a fighter that would perform better in 5 rounders. He's not great yet, but he's very good and he's only going to get better.
