When BJ Penn came back to the UFC I thought he should fight Hughes immediately for the title. BJ won it from Hughes legitimately in the cage. Hughes got the title because of "business" which stripped BJ of the belt.
Now when BJ returned he decided to take on the #1 contender and then go for the titleshot. I know he lost to GSP but I think it is well within his right to get a titleshot even after that loss because if he requested one on his return he should have deserved it anyways.
I really like GSP and as much as I would like to see him fight Hughes I think he shouldn't rush into it if he has an injury. This is second shot for him and it was already a tough enough road for him to earn this shot so I think he should wait till he is in perfect shape before taking the fight. Don't try to "man-it-up" and pretend all is good and fight Hughes injured. I, for one, don't see that as brave but stupid.
So unless GSP is fully healed he should opt to wait and I vote for Hughes v Penn for UFC 63 to decide to legitimate champion and GSP gets the titleshot when he is fully healed.
UFC make it happen!
