GSP, because he is just way better
Rory, since I think he's improved since their first fight and has made the necessary adjustments to avoid gassing and getting caught
Hendricks, because I have questions about Ellenberger given how mediocre he's looked in his last couple of fights (though since both guys have the same basic gameplan, I could see Jake taking this fight in a decision)
Showtime, but man, that's a tough call. Pettis/Miller would be an amazing fight, I'd love to see it some day.
Edgar, since I think Aldo will be rusty after a year-plus layoff.
