In recent years when you have guys who are 150 pounds and 5'3 (such as Rey Mysterio) going over someone like the Big Show .... wrestling loses its believibility.
Sure the IWC don't care .... as its match quality most smarks care about.
But for people who are not die-hard fans .... seeing the little guy beat the big guy, for them its like seeing David beat Goliath. They can't believe what they've just seen and dismiss it.
'That really happened... no way? As if that would happen! what a load of rubbish'
Its not so obvious when Punk wrestles smaller guys... but against the Rock, the differnece in physique was obvious.
How believable is it to the casual wrestling fan to see the 'Average Joe' beat the guy who looks like a wrestler?
Sometimes I find myself defending wrestling to non-wrestling fans... they just take cheap shots 'Oh its so fake' .... 'that guy would never beat that guy' ...and it doesn't help when the 'believebility' factor is gone
