The biggest phenomenon in MMA today is otherwise knowledgeable fans hyping a fighter after he beats a few scrubs in a row. But Mendes is definitely top 10. He's beaten Koch, Yahya, Swanson, and Elkins... He's got a lot of cans on his resume but there's some talent sprinkled in there. He's definitely not "the man to beat Aldo" or anything.
Also my favorite MMAmath right now is "Pettis got beat by Guida who is like Mendes [somehow?] so Pettis would definitely get beat by Curran."
