Griffin is done and has been for awhile. I think Ace has potential but needs to fight more. He's older than most guys but he's in great shape. He can hang with the best of him.
As far as p4p. Atm I have in this order...
This guys are tried and tested and have done very well against the best in the world. They dont always win but when they do, they do it well and are all champs, some in multiple divisions and multiple forms of Martial Arts.
1. Anderson Silva
2. BJ Penn
The rest are untested but I'm going to list who I think has the skills to be on it and last.
5. Jose Aldo
6. Cain Velazquez
7. Johnny Bones Jones
Everyone else is questionable at this point. Did I miss anyone? lol. Let me know. Where you at with rankings?
