Don't get me wrong, I think Floyd could've beaten Casa but Casa was that dude at lightweight during that period. Granted, the fight everyone was asking for was Corrales and Floyd and Floyd dished out one of the all time great ass whuppins ever witnessed. But technically speaking and experience wise, Casa was the guy who would've given Floyd the true test at lightweight. I also think Floyd could've beaten Kostya rather easily since he is way too disciplined to make the mistake that Zab did in getting cocky. Zab was whuppin his ass in tat first round and Floyd could've done that for twelve rounds against Kostya but when a dudes timing is that nasty.......I mean he threw that right hand on Zab and Sharmba where they were going to be and the punch and Zab/Sharmba, got there at the same time, timing like that is rare. Floyd prolly said "why risk it". We'll go up to welter. Also call me crazy but I sincerely think that Cory Spinks would've given Floyd a problem initially, probably wouldn't have ever beaten Floyd but Spinks was cute and slick and very fast and technically sound and a southpaw. That would not have been a money fight either, would've been like watching paint dry or a plant grow.
Freitas had donkey kick power in his punches when him, casa, and pbf had belts at lightweight. I honestly think they both would have given him trouble for the simple fact they never fought. The chico fight was not all pbf than it was chico's issues. He drained himself to drop weight and he was going to jail. It was very bad timing. Plus PBF was all in his head with that beating women drama which is just like the manny steriods stuff. Corey I agree would have and still would be pbf problems. But that is the type of fighters bf stays away from. Samething with kostya and Shane. To me both fighters could have handled themselves well against them. Kostya was a beast. He made everybody he fought pay a deadly price. He did jab his way to victory. He was hurting people.
