Besides a match with Jay Heiron, the options are not many for Strikeforce welterweight champion, Nick Diaz.
I personally don't doubt a Diaz victory in that fight, though it is a worthy challenge for the title.
Besides a rematch with Thiago Alves, there are not a lot of matchups involving Jon Fitch that could be considered headliners.
His workmanlike style hasn't made him a favorite to many fans as of late, and his refusal to fight any of his teamates in the UFC has limited his options.
I could see Fitch being the biggest UFC asset to change hands since Dan Henderson.
It was well-documented that he hasn't always been on the best terms with the higher ups in the UFC. He was briefly dropped by the organization when he hesitated to sign over his likeness rights to the UFC when they were in production of their latest video game. And Dana White has made no secret he doesn't approve of the whole "teammates don't fight teammates" philosophy.
Fitch however, does have three fights left on his contract, so this could be some time from now.
Also, Diaz seems very content outside of the UFC.
Both of these welterweights are at the top of the division, but I would have a hard time believing either of them could top the champion, Georges St. Pierre.
Nonetheless, a match between these two would be very intriguing, especially if scheduled for five rounds.
