BJ receives offer he can't refuse. Why?

Did Dana force BJ to take this fight, against his longtime friend, training partner, and fellow medicinal marijuana user? Phone Post

$ + potential title shot = my guess

Because assuming GSP beats Condit and when bj beats OG Kush, it puts penn back in title contention. I'm a huge penn fan but don't want to see him fight GSP AGAIN

offered him a significant amount of money to accept a new opponent on short notice.
