If GSP was smart he would take the Silva fight first. He would collect on a huge paycheck that he wouldn't otherwise get if he were to fight Hendricks. GSP should go get KTFO by Silva, retain his title, and get KTFO again. If he were to lose to Hendricks first, the Silva fight wouldn't make as much sense as a "superfight."
Believe it or not, I AM a GSP fan. I just think he's screwed either way.
