Eddie Wineland
Michael McDonald
Scott Jorgensen
Renan Barao
Yves Jabouin
Brian Bowles
Miguel Torres
Brad Pickett
etc ...
Based on UFC wins, McDonald.
Based on records, Barao.
Barao is clearly the top contender.
1st - Barao
2nd - MacDonald
3rd - Pickett

Brad Pickett cause hes English but Barao deserves it on record
epwar - Based on UFC wins, McDonald.
Based on records, Barao.
Barao has beat Pickett and Jorgenson. Both are better wins than Torres right now imo.
Renan Barao is the obvious choice
Renan will murder faber and then we will never have to see but chin fight for the belt ever again 
Kimo Lives - Renan will murder faber and then we will never have to see but chin fight for the belt ever againThere is still flyweight...
people are forgetting about Menjivar
junobeach - "Whoever has the least chance of beating him" - Zuffa LLCLOL so true
Chris27 - Barao is clearly the top contender..
UGCTT_ZJJitsu705 - people are forgetting about Menjivar
not forgetting, but I dont have him in the #2 slot behind Faber
Clearly Barao unless they go with the unlikely step of bringing in Bibiano Fernandes.

Barao.
McDonald vs Menjivar fight the winner
junobeach - "Whoever has the least chance of beating him" - Zuffa LLCLMAO.... So true
