I'd add Gamboa... you just never know what will happen... I wish he'd have the showboating style outside of the ring, I miss the Hamed entrances. But Gamboa is not like that. Not a smile, not a single thought on looking good in his entrance. He goes to kill or get killed. Very serious dude, too serious I might add.
if i may add.. RJJ on his prime!!!! Though he is still exciting to watch now.. it's nothing compared to his younger years!
