He didn't say for sure he wouldn't fight anyone before GSP, nowhere in the article does it say Condit refuses to fight anyone but the champ.
Condit is a warrior who doesn't duck top competition, doesn't duck wrestlers, doesn't duck champions. If Dana says "Condit, fight the winner of X" or "Fight X because it's a huge fight," he'll do it.
I think a five round fight with Ellenberger would be great. Give Condit a chance to "avenge" the split decision win. IMO he'd probably finish Ellenberger in the fourth but I bet it'd be a wicked fight, and it'd be good to see if Condit can realistically stuff a power double in the first 1-2 rounds.
