I'm not oferly concerned for Iron Mike's welfare. I think Tyson is liable to do Logan a lot of harm inside two rounds if they are permitted to genuinely go for it. I boxed in the army (winning the grand total of zero fights) and Tyson gives up a lot of size, reach and two years or age to me, and I'd not want to face him in the ring.
Size, reach, fitness, all lovely stuff, but you're either fundamentally wired up for combat or you're not. You're psyche and synapses either make you well suited for it or they don't. Tyson most definitely is, from what I've seen of his multi named opponent, he isn't. It can't be taught.
Paul might take it, but he's a fool if he thinks his age advantage will take him too far. He's going to have a proper fight on his hands. As it is the number of rounds etc have been arranged as a nod to the fact that Paul has never had a long fight, and slightly heavier gloves blunting the punches slightly will probably protect Paul from Tyson more than the other way round.
Certainly the whole set up seems to be intended to level matters by negating Tysons two biggest advantages, his fearsome punch and his experience going the distance. If Paul were any kind of walkover the organisers wouldn't be handicapping Tyson in this manner.
