If Machida beats Couture, I'd like to see him fight Griffin.
I think we'll see Rua vs Jackson II sooner than most think. I reckon if Jackson beats Hamill with no injury, Dana will immediately set up the Rua fight for August, which is roughly when Rua is fighting next, and Jackson will be able to go straight back to camp and stay in shape for it.
Winner of Machida/Couture vs Griffin then fights winner of Jackson/Hamill vs Rua, possibly for No.1 Contender.
Meanwhile, Davis fights Bader and the winner moves up with the others. Jones vs Evans isn't actually happening until the later part of the year, the division can easily sort itself out before then.
