It's tight. JDS was the number 2 at that point and it was 1/1. People were split on who would win. We wouldn't see some much butt hurt if it wasn't seen that way. We still have fools constantly posting JDS has better striking, so JDS was perceived and still is perceived as threat to Cain.
Then again it was pretty fast for a rematch after the beating Cain handed JDS so I could see why a lot of people would say it was too early.
Still JDS was number 2 and who else was cain going to fight? Maybe werdum but most wouldn't say he was number 2. I'd always want to see the 1 and 2 guys fight personally.
