I don't expect the most objective comments here, but as the title suggests, and you've got 5 secs... Ooooo, I say Floyd UD!
if it goes 12 rounds and the scoring will be based on number of punch landed, ill root for pacman UD. im still rooting for late rounds TKO, roger will throw in the towel. you will hear roger asking jr "wwooooonnnneee mmmmooore rrouuunnd?"
Any legit welterweight KOs Floyd easy. Pac won't even need sparring he should go shoot another movie instead.
