I'd like to see how Casa looks against Santa Cruz because he looked iffy against Chico last time out. Also like to see pac at 135 but I think he'll be fine, he's been weighing in at around 144 lately on fight night, Juan only weighed 142.

Juan pts-too active for an old Casa
Juan pts-would back up Pac, Pac's not used to fighting a guy like Juan, still this is a bit tougher too call for me
Pac pts-I'm not just not sure about Casa anymore, another tough one to call as Casa could frustrate Pac and outpoint him
Juan TKO/KO
Manny TKO/KO
Casa pts

Obviously I don't think of David Diaz as on these guys level.
