Like someone mentioned earlier, use speed to get to the legs
to get them to the ground. If someone has a steel jaw and can take a hell of a punch
then you go for the temple. Tyson knocked out a few guys or more with temple shots.
Then there's always choking them out although with Andre you would most likely
need long arms.
Here's the closest scenario to this thread and it took a very skilled 230 pds. pudgy
Fedor 2 minutes to win. Fedor is really a lightheavyweight that dominated the heavys
for a long time. By that I mean his structure and muscle mass is that of a 205 lightheavy
and the extra weight was not quality weight but he was so skilled for his time he constantly
beat bigger opponents. MMA has evolved though and in this day and age
in the UFC he
would probably fight as a lightheavy if he was just starting his career now.
