I, too, was a huge Jones Jr., fan back in the day. For this fight, it looked like he knew damn well he wanted no piece of Tyson. As another poster mentioned above, he hugged Tyson a lot. It was nearly the entire fight. If he'd tried going toe-to-toe with Tyson, it would have gone very badly, very quickly. It was still fun to watch and the decision meant nothing to me going in, so the clearly bogus "draw," didn't bug me a bit.
Re: working the body, I think it was both by design and by necessity. He could not separate himself from Jones. I imagine that if this were a real fight that a) the ref would have done much more to keep Jones off of Tyson (physically separating, penalizing) and/or b) Tyson would have done what he had to do, i.e. push Jones away, nail him below the belt, etc., in order to create his own separation.
But those body shots were punishing. I think if they were 3 minute rounds, Tyson would have at least knocked Jones down by the 6th or 7th round.
