im not taking sides because i kind of agree with both of you. Boxing, does need a lot of practise, i see kids coming down to the boxing club all the time thinking they are ali after about 4 months. It takes longer and, yes i would say that boxing has much crisper technique than most cage fighters/ k-1 fighters. Boxers, and just boxers, will as a general have better punches than cage fighters, because thats all they can do, they cant kick etc. so they have to make sure that they have very good hands.
On the other hand, i think that teaching tyson/a good boxer a sprawl and some ground work would make him win against cage fighters. Like boxers do, cage fighters will see that the opponent has good hands, and knows some ground work. So,unless he knows he also has as good/better hands that the opponent he will try and take it to the floor, where he feels more comfortable. Boxers and cage fighters are both good fighters.
I think if both the fighters are good, its more to do with the person, so thats why tyson would have been a great cage fighter.
Then again, tyson was known for his amazing hands, not chin. He may be devastating with 4 oz gloves, but then again, so are other fighters, so its hard to tell what might happen.
I sometimes think that if tyson had trained in other things like muay thai, and some ground work, he might end up something like Melvin Manhoef?
