Speaking of Sabu, can someone point me to some of his good matches? I'd like to think that he's more than just a botch machine.
You have to understand why that is. He is an innovator.
Sabu isn't botching basic bodyslams and suplexes like a bad wrestler, when he botches something its cause he is trying something relatively new or dangerous. He is the type of wrestler that decades after he retires new wrestlers will be doing moves he created or popularized. They will know and understand how to do those moves cause he sorted out the angles and techniques for them.
The other thing is the level of skill involved.
I don't fault Brock for botching a shooting star press. Thats hard to do. Especially for a 300+ dude halfway through a match. But I would be able to pull off a shooting star press before I could do some Sabu shyt. He is a 50 year old man running and jumping off a chair to land and perfectly balance on a springy 2-inch rope before doing a 360 leg drop to the outside of the ring through a table. Give dude a break.

Other wrestlers his age are in the center of the ring doing headlocks.
Gotta appreciate.
The other thing is, when a safe generic wrestler does a slam or chop or suplex incorrectly, a veteren or peer can correct them like 'hey, you do it like this'
but when Sabu did something wrong (or now when Teddy Hart does something wrong) they have no peers. No one else is doing what they did/do so they have to figure it out themselves. Thats one of the reasons the Hardyz are phenominal innovators... they had each other.
