If Floyd was the only fighter allowed to wear those gloves, then it'd be unfair.
But Zab could've wore 'em too if he feels they'd give him an advantage.
Now if Zab knocked Floyd out, the argument would be, "It's not fair, Zab's gloves were more compact!"
Both gloves have their ups and downs.

I swear if Floyd's gloves were black there wouldnt even be a discussion right now.
The white gloves look 100 times bigger than black gloves on tv.
