It would be a hard fight for both. None of this gatti and tszyu comparing shit coz gatti is nothing compared to tszyu. Gatti didnt have the weapons to deal with pbf...tszyu does. Tszyu is not a brawler and does like to box and this fight would be a chess match. Tszyu has the huge right hand which if he lands could hurt pbf. I wouldnt make a pick unless this fight happened but judging on the way tszyu handles boxers then id have to lean towards him.
