Which would be the greater upset?

[The Taxman]

Sonnen via sub (fear)

 

[TJC]

Sonnen beating Jones.

 

[MP15]

Chael because GSP has been finished in round one by TKO before and almost got TKO'd against Condit. Though Jones himself almost got submitted in round 1 against Vitor, I doubt Chael has the same skill as Vitor but who knows. Either way, Chael finishing a fight is actually quite impressive.

What would trump those upsets is if Bisping outpoints Anderson Silva.

 

[acidic]

Sonnen.

 

[Otto!]

Either happening would make me question reality.

This.

Chael Sonnen would be the bigger upset

I know Diaz will beat GSP, I don't know about Sonnen

 

[Codpiece]

Both would be big upsets, but Sonnen subbing Jones would be simply incredible. My mind would be boggled! Could you imagine Sherdog right after!?
