Kongo would brutally murder Chuck if they fought.
Kongo is a technically sound striker. What happens when someone technical forces Chuck to fight standing up?
We saw him get kicked a million times in the Jardine fight.
We saw him get TKO'd by Quinton Jackson.
We saw him get KO'd by Rashad Evans.
With Kongo's technically sound striking, Chuck's getting knocked out.
Chuck needs fighters to run at him wildly with hands swinging everywhere. Kongo wouldn't do that. That's a reason why Chuck matches up much better against Shogun, Babalu, and Wanderlei.
If Chuck fought the likes of Quinton Jackson, Lyoto Machida, Anderson Silva, or anybody else who has well defined Boxing/Kickboxing, it would end in brutal fashion.
Can you imagine how badly Lyoto Machida would pick Chuck apart? Lord have mercy.
