No. He's nowhere near the realm of big enough. P4P I might actually agree. Give him a year to put all of his skills together and round everything out and quite honestly he might seriously whoop some ass. It would be an enormous mistake to do so though. As great as he is, he would be throwing money away to move to 135 in the UFC. As great as those fighters are, there just isn't any money for him to make there.
145 is too big for him, and the biggest money fight for him would be Aldo....who is pretty fucking huge and strong. To fight Conor would be insane. Conor is enormous compared to Loma. Grappling prodigy or no, he's not tossing Conor anywhere, and he's ending up on bottom getting ground out most likely.
I'm a huge Loma fan, but I don't see it in 100 years. He's just too little.
