I'm pretty much with Eugene here. Superfights to me don't make any sense unless there's semblance of the winning fighter's desire to represent the weight class of the guy he just beat, and even then, with no title on the line, he'd have to work his way to a title shot, or rematch the guy he just beat in hopes that he beats him again.
I don't watch boxing, but I usually follow the news closely, and last I saw, nobody was clamoring for Floyd Mayweather to superfight Andre Ward, and those two are considered to basically be the #1 and #2 pound for pound best boxers in the world (and oddly enough, I think 15 pounds separate their fighting weight classes.) What is there really on the line? Titles? Legacies? I don't mind calling this a cash game. GSP and Silva have nothing to gain from this fight outside of a quick payday. If GSP loses, he has to build his legacy back up while Silva can coast into retirement. If Silva loses, what he worked 6 years to obtain goes by the wayside. Not to mention, the loss sets either guy back in terms of being a draw and selling shows. The UFC can book boxing-style cards around either guy's fight where you can get away with co-mains like Sean McCorkle vs. Stefan Struve because the majority of buyers are just there to see the main event.
Just look at what happened to Manny Pacquiao when he "lost" a few months ago to Timothy Bradley. The Mayweather/Pacquiao talks have cooled down, and I haven't heard it mentioned outside of sports journalist circles since summer, when it was all I'd hear out of boxing media and fans. Nobody outside of loyal followers of the sport care how you lost, or how badly you got screwed. All they see is the red mark in your win/loss column.
GSP has no problem fighting guys smaller in size
I don't buy into that. Of GSP's last 7 opponents, all of them, with the exception of Thiago Alves are taller (Alves is an inch shorter) and all are heavier on fight night. Alves, in fact, used to weigh around 195-200 on fight night, and in his last fight against Kampmann, was in the neighborhood of 205 when he walked into the cage after he started a cutting routine with Mike Dolce. None of GSP's smaller opponents have been hand picked. They all had specific ramifications on his career at the time:
-Sean Shark: Had always fought in the UFC at Welterweight at the time - Winner was to be vaulted into the Welterweight Title Picture
-Matt Hughes: Hughes was champion the first time they fought. Second was for interim title.
-Matt Serra: Forced title shot due to Serra's TUF win. Also had to beat Serra to win the title back.
-BJ Penn: First time was a Welterweight Title Eliminator (Penn had also beaten Hughes and was a one time welterweight champion by then.) Second was Penn continuously calling out GSP until he accepted.
I think the animosity towards GSP (and believe me I feel the same way) is that he is a relatively safe fighter. He stopped taking chances after Serra got him. He has been mostly lay and hump into submission.
I'm sorry, but when you're at the top of your division, your opponents should be adapting to your style, not vice versa. I don't even begrudge Ben Askren for his fighting style. He made it to the top of the mountain, and his job is to stay there at all costs.
