I read they greased his back heavily and commission people had to run up and wipe it off. Ah well, shame to taint a perfect fight, he would have won anyway.
There are alot of different theories. Penn has pretty much accepted that GSP is better though, it's mostly his corner trying to make it a big deal.
Penn is reportedly considering retirement now.
Arlovski made $1,500,000 for getting his ass kicked by Fedor
GSP took in about $400,000 (both figures not including sponsors ETC)
