Pretty sure I've typed that myself word for word a few times here and on other forums. Agree 100%.
I think you are underestimating Diaz's boxing. He may not zip in and out like Frankie, but he can still out point BJ boxing. BJ needs to make this an MMA fight. Mix in a bunch of kicks, knees, clinch, takedowns. Stay active.
I have no idea who I am rooting for. I really, really, want to see Diaz-GSP, and Penn-Condit. Even Condit-Diaz down the line would be great. I don't want to see another Penn-GSP fight though. It would be better if the Condit-GSP fight was first. Then I would know who to root for to get the right matchups.
