Lupe is damn good, he kind of looks like a robot though. He smiles way too ****ing much, it's creepy.
Joe Martinez is pretty decent but certainly not the next coming of Michael Buffer.. TBH, I haven't noticed any current announcer who will be able to fill the shoes of Mister "Let's Get Ready To Rumble!"
There will be no next Michael Buffer. The only other announcer to have even close to a known tag line is Jimmy Lennon Jr. with his ITs SHOWTIME! But none will ever come even close to the notoriety of Buffer's RUMBLE line.
