Berto, doh. Simply because he is young, hungry and in his prime. He has got speed, power and is a natural 147 lber. He is that kind of boxer with that slick style that Manny has never faced before.
Berto is currently the best opponent at 147lbs but he is far from slick.
No agenda and no BS. Who is better at 147?
jmm has no business above 135 lbs.
mosley/berto is a 50/50 fight, but berto due to his youth has to be considered the frontrunner.
