Yeah - I totally agree.

If size really was everything, why weren't Valuev and Carnera in the tournament.

Dempsey and Louis absolutely butchered Willard and Buddy Baer (who were both at least 6'6"), just as Ali did to the similar sized Ernie Terrell. Tyson handled the Bonecrusher and Tucker with general ease ... though a great deal was made about the fact they actually landed a punch (!)

Skill, technique, heart, conditioning, talent and toughness will always out against someone who has less than these, even if he is bigger.
