I am not a PBF fan. He fights at 147, but he only fights fighters who naturally fight at lower weight classes. He is, however, undeniably good. It follows that he will beat Marquez easily.

The reasons you stated for the why the fight will be closer than expected are all valid reasons for why Marquez is a solid fighter, but the fact is that PBF will be too big. It's not like he is big and slow; he is big and fast. Faster than Marquez. Bigger and faster? I give Marquez little to no chance. That said, good for Marquez, he deserves this pay day.
