The funny thing, is if you were all asked before the McGregor fight if Aldo was in his prime, you would have said yes. In fact, 95% of sherdog thought Aldo was going to murder (literally) McGregor.
Conor took Jose's soul. You don't go from ''Greatest FW of all time, absolute prime, top 3 P4P'' to ''out of his prime, had too many fights'' within a 2 years span. Like I said, ''prime'' is mostly a myth, unless we're talking about guys north of 35 who have had lengthy careers. Aldo is just starting to fight better men and losing to them. Prime Holloway > Prime Aldo. Prime McGregor > Prime Aldo.
