Featherweight division? I think he would be exciting and top 10 with his style, he'd fit well and give some guys problems. Haven't seen any posts but imagine if UFC bought bellator like all other orgs, who would come over and do well, let's say top 10? 
I feel he would do very well
Fine.
Kinda weird question.
The rules are exactly the same.
About the same as any guy in the UFC his level in Bellator.
Depends on the fight, depends on the night. 
Mediocre
A game Pitbull? Game over man, game over.
