Just missed the end of the last - I think it that 'Father Time' factor definitely may play a part, though..Mendez was a heavier wrestler; more grappler than striker - Alvarez had a decent boxing base out of 'Philly' area -- So I may lean slightly Alvarez, particularly if he has a great than 3" reach advantage --I think you may be money with that Perry pick --- Luke has the father time factor... but also ...Luke mediated distance with kicks...Perry has ZERO issue fighting in a phone-booth
