I gave it a clear 49-46 for Edgar.
Dude isn't going to get another LW shot. Bomb Dana to let him know that decision was BS and give Edgar an immediate shot at Aldo.
Frankie is a beast to be 160lb fighting these guys with a huge weight advantage over him, and being able to bring it to them.
Dana doesn't judge the fights. 
Edgar/Aldo would be a fun fight.
