Bj penn is definately not overated and i think hes the most dangerous opposition out there for gsp along with thiago alves and for anyone to say gsp will dominate him is just plane stupid, i expect a very competetive fight that gsp will win by decision or maybe stop bj late on due to his size nd bj penns suspect cardio but ill tell u one thing gsp will get all he can handle in the first half of the fight
