Perez is listed as 6'0" on boxrec but i think thats wrong. I was looking at facebook pics and he had a pic with Alexie Acosta ( Or Collado, same person) who is a batamweight and Perez only had like an inch on him.
Its the other way around for me!! Im not impressed with Helenius. Im more impressed with Perez, but based on accomplishments Helenius is better.
You're impresed because he's all action and business, but Helenius has the phisical advantages and we recently saw that payed a good role in makeing David Haye's toe look bad.
Physical advantages mean nothing if your opponent neutralizes them or if you dont know how to use them. Prime example: Paul Williams vs Erislandy Lara.
Perez really needs to work on developing elusive headmovement to slip the jab as he closes the distance, because he will inevitabley be facing tall jabbers later in his career. I also think he needs to keep his weight down, sometimes he's quite flabby when he fights at 240lbs+, & that will certainly harm his speed, explosiveness & stamina.
I also think Perez needs to changes his flicking, range-finder jab into more of a pumping, shotgun jab, for setting-up bombs as he closes in.
It's highly unlikely the managers of Perez & Helenius would risk their unbeaten puncher prospects records against each other right now. I think we'll have to wait a few years for them to meet in the ring.
