Apart from his fight with with Tim Kennedy.
If Bisping gets by Munoz, and Machida gets past Kennedy this could easily be a top contender fight. Bisping has been in and out of title contention, and with Belfort fighting Henderson at 205, this fight makes the most sense.
4. Lyoto Machida vs Mark Munoz
This a very good stylistic matchup for Machida, considering how well he handles wrestlers. (Apart from Phil Davis)
3. Lyoto Machida vs Jacare Souza
Words can't even describe how amazing this fight would be! After his first round massacre of Okami, I think Jacare would definitely pose some challenges for Machida. Ultimately this fight would be determined by if Jacare take Machida down and submit him, but I don't think that would happen and Machida would have the advantage on the feet.
2. Lyoto Machida vs Vitor Belfort
This super fight would pit two Brazilian superstars, who have publicly announced their disdain for each other. Machida would look to stay away from Vitor's fast hands, and night ending headkicks. Overall this would come down to if Machida could counter punch his way into a victory.
