Everyone is hating on penn and they don't even realize it.
"penn needs to get his act together"
"If penn trains hard...."
Do you guys realize that Penn was dominating hughes and it is very likely the only reason he didn't continue that dominance was because of an injury? Everyone gets that If the injury didn't occur, hughes would probably have lost 2nd round. But what people dont' get, is that its very possible that BJ trained well enough so that he would have continued to dominate 3,4, and maybe all 5 rounds of that fight if it went to decision.
BJ Penn is a natural talent and has had some rough luck; if he just comes back with what he already brought vs hughes; I find it unlikely for anyone besides GSP or a completely matured Sanchez(under fedor's training) to compete with him. To be honest I think the only man as skilled and smart as penn is Fedor himself.
