Id say Penn wins in round 3 by submission or TKO. BJ is really evolved into a total fighter with his new cardio. Short of them bringing over Aoki I dont think anyone can really challenge him. I dont really think Aoki would be that big a challenge for BJ, but probably the biggest test I can come up with for him. Aoki really broke that guys arm recently got more respect for aoki after that.
Personally I dont think Edgar can grind BJ maybe a few years ago but in his last 2 fights hes really showed cardio improvement. Edgar imo has to grind and wear down BJ to have a chance. I dont blame the UFC for putting together this fight because Frankie is the top contender atm. The only way I can see Frankie winning though is the ole 'fighters chance'.
