I was never that impressed with Munoz and I think his former top 5 ranking was more due to other contenders losing and dropping down the ranks and guys like Vitor not being ranked yet as opposed to him actually being a legit top 5, but he's still a pretty good fighter who can make for some fun fights, and be a tough test for upcoming fighters.
