Between the both of them who would win in a wrestling match fight i would say will hands down he was nothing to play with when he gets angry.

uncle Phil in the 90s

Will in 2013

Uncle Phil outweighs Will like 3 to 1 - if we are talking wrestling (and i am assuming here we aren't talking about WWE fantasy rules) then Uncle Phil would destroy Will. and then sit on him...

The reason i said will would be more of a match for his uncle phil wrestling was that he looked pretty pissed off to the max when he stormed out that back door after he got into an argument with phil and vivian in the episode where his father walked out on him at the last minute.
