Would be a great all time fight.
They are both good on the ground. Both have good standup. Condit is more diverse with kicks and knees while nick's hands are far superior. They both also have great cardio and length. I dont see either subbing the other. Neither has great td's or tdd, Carlos could get nick down and win on points but i see them standing. Carlos could pose some problems with his kick and his diverse attack, but imo Nick keeps hitting and eventually overwhelms him in the 3rd or 4th. This would have to be a 5 round fight.
Id love to see both of them fight bj as well. Unfortunately i see them suffering the same fate against GSP. They both can out-strike him and are better on the ground but will get taken down for 5 rounds.
