I think GGG can make 154 pretty easy, but I would advise him against agreeing to the 162lb day of the fight stipulation. This would be the best fight possible to me. Floyd's speed and mobility vs GGG's relentless pressure and much bigger punch. I can see Floyd out speeding him and getting the decision behind pot shots and some really uncomfortable moments. I also think that GGG can seriously hurt Floyd with either hand, even if he catches him high on the head. Great fight, but not really fair to ask Floyd to take that monster on.
