Serra please drop from 170lbs.
Aldo will reign over that division 
I know Aldo rules the division but Serra at 145lbs is dangerous for anyone. I agree that Tyson should drop as well.
It's physically impossible for Serra to cut to 145 anytime soon.... and if he refused to go to 155 what makes you think he'd go to 145?

Im guessing he walks around at a bulky 180lbs so its not physically impossible to cut to 145 by any means. He isnt getting any younger so if he wants to make one last run at the title this is the weight class to do it in imo.
