I would like to see fight between Chris Horodecki vs Melvin Guillard.
They are very similar in styles.
I would also like to see Urijah Faber and Jose Aldo go to the light weight division. These would be interesting match ups.
Faber vs Penn
Faber vs Lauzon
Faber vs Edgar
Faber vs Shalorus
Aldo vs Penn
Aldo vs Lauzon
Aldo vs Edgar
And of course everyone wants the GSP vs Silva fight. That's obvious.
