I think Diego should be a small favorite but no Huge favorite by any means. Riggs is 12-3 in his last 15 fights with wins over the likes of Nick Diaz, Lytle, Joe Doerksen, Kendall Grove, and Jason Von Flue. They may not be headliners but they are some tough fighters. Riggs three loses during that time have came against Matt Hughes, Ivan Salaverry and Mike Swick all very talented fighters. So with all that being said Im taking Joe DIESEL by KO in the 2nd. I think finally being at a constant weight and natural maturing will turn Diesel into a serious contender in 07 after all the guy is only 24 with 33 pro fights under his belt. Hopefully he doesnt burn out to quick.
