I didn't see the broner vs perez match, but will watch it according to what i have heard.
But i saw alexander vs maidana.
Maidana is good, that he is able to get into his opponents if needed to get the points he needs with power punches and the opponent can't do anything.
But this time alexander was "great", in his speed and power he is definitely suited for 147 and maidana said he was not suited for 147.
alexander vs kell brooks would be good to see.
