It's no show of respect. It's self-preservation. Paul knows how boxing fans feel about Tyson, and hitting him in this geriatric condition will only drive more people to hate Paul. This is why this was such a dumb fight. There's no real way for Paul to win. If he wins, he's hated for beating up on legand way past his prime. If he loses, he lost to senior citizen. Tyson, on the other hand, is doing this purely for the payday. He has nothing to prove, and will be a winner no matter the outcome. Who cares if he doesn't beat the dude who's 30 years younger than him? He's waking away with millions.
