When making a lot of matchups like this I take a few things into consideration; Rankings, Winners & Losers, Fun fights, Fresh matchups, & UFC vs Strikeforce. Using that criteria I came up with these 8 fight:

TEN WINNERS TO MATCH UP: GSP, Hendricks, Maia, Ellenberger, Rory, Saffiedine, Lawler, Kim, Mein, Story

1.) Georges St. Pierre vs Johny Hendricks

2.) Demian Maia vs Jake Ellenberger (#1 contender)

3.) Rory MacDonald vs Tarec Saffiedine

4.) Rick Story vs Robbie Lawler

5.) Dong-Hyun Kim vs Jordan Mein

SIX LOSERS TO MATCH UP: Diaz, Kampmann, Alves, Condit, Kos, Marquardt

6.) Nick Diaz vs Martin Kampmann

7.) Carlos Condit vs Thiago Alves

8.) Josh Koscheck vs Nate Marquardt (Loser leaves town)

Fights like Erick Silva vs John Hathaway, Jake Shields vs Tyron Woodley, & Gunnar Nelson vs Mike Pyle are also significant fights that are currently scheduled to take place & help shape out the future of the division.
