Machida and Shogun are right to decline, they are fresh off fights and Shogun in particular is already preparing for his next bout, still under suspension.
Why should they bail Jones out? Jones had an opponent ready to go in Sonnen, he pussied out. No matter who he fought, he was going to be way more prepared.
Gustaf should have been first stop IMO, young gun on a streak, just like Jones was when he got his shot. Gustaf hasn't been mentioned at all though, looks like they did not ask him.
Don't diss other fighters for declining though, everything Jones does is disrespect. 'It's risky to fight Sonnen on 8 days notice, but I might consider fighting you or you.'
Get out you prick.
