GSP lost his first title fight and also lost his title to Serra remember? But as I said your opinion on his losses to Diaz, and draw to Fitch just go to further my point that its foolish to move up because if you have less than 100% success then half the fans turn on you regardless of what you accomplish at that weight. There is no win for any fighter because fans don't respect the challenge and the drive to fight the best, for all the talk they just turn on you and throw you under the bus. As I said every post you make were you try to discredit Penn just furthers my point. I am a fan of both Penn and GSP and think they are equally great fighters but one took that chance the other hasn't and look at the way people view them.
But that's a chance you have to take. I'll go into why GSP won't drop in a minute, but lets assume that GSP then even drops out of the top 10 of all time. Isn't that a risk that he should be willing to take.
Win:- Become the greatest of all time.
Lose:- Drop out of the top 10 all time.
Don't Fight:- Stay top 3 all time.
Being the 2nd best and being the 10th best doesnt make a difference if you had the oppertunity to become the best.
And regarding what you said about "The Diaz and Fitch fights prove what i said", GSP wouldnt be staying at MW. If he lost to Anderson, you wouldnt see him challenging Weidman and Bisping. People turn on you if you keep losing fights. BJ Penn lost a lot of fights close together, two at LW and two at WW. GSP would be having one fight (at a catchweight).
Okay, lets take Diaz and Fitch out of the equasion.
If GSP lost to Anderson, came back, beat (just examples) Condit and Koscheck and then lost twice to Diaz, that would fuk up his legacy. The Anderson fight alone did nothing, but the two losses at his own weight class would. BJ Penn came back to LW, defended his belt twice and then got beat two times off of Edgar. That was more harmful to his legacy than the GSP loss. I'm sure the majority of fans don't even care that Penn lost to GSP because lots of people have lost to GSP.
