by making the floor red we wouldnt be able to see the blood being spilled all over the canvas. i dont know about you guys, but i think the blood is pretty violent looking not to mention disturbing. its easy to say "who cares, its a blood sport" but these athletes are humans too and they have families like you and me. they dont like seeing them hurting and neither do i. its different when it your own blood also. i thiink this makes it more friendly to the average person and could help make this sport one of the biggest mma organizations in the u.s.a.
