This thread has the makings of John McEnroe written all over it. It cannot be serious! John "the disease" Ruiz vs Muhammad "the greatest" Ali. Sounds like a damn monster movie! Really folks, spare me the cheese because the disease shouldn't even be mentioned in the same breadth as Ali. The only fight Ruiz wins against Ali is a pure holding contest, and I'd bet on Ruiz finding a way to complain to the ref even when Ali's is beating him to the hold.
Ali would definitely lose a wrestling match against John Ruiz. In a boxing contest, it's not even worth debating. Ali would slice and dice Ruiz until the ref is totally sick of hearing Ruiz complain. Wrestling is John Ruiz' forte, not boxing.
