Collazo is a good fighter without doubt and a tricky opponent for most at 147 but P4PKIng has it right in my huimble opinion,the guys he mentioned would beat Collazo. The problem with Collazo is he is not a big enough banger to stand toe to toe with the big boys at 147,and he's slick but not slick slick to make him elusive.(although I don't think Baldi/Judah would beat him,replace them with Quintana andWilliams.)
