Matt Brown is different than Melvin because he's actually getting better and has heart, doesn't fade or brainfart like Melvin was prone to doing.
And for all of this favorable match up talk, say what you will, but the level of competition Brown has faced in this 7 fight run is better than the competition he was facing prior to it, and instead of being .500ish against that level, he's finishing these guys in brutal fashion.
And on that favorable match up note, I'd say his biggest weakness is sub guys, not wrestlers, and Silva and Pyle are certainly capable sub guys, and Brown beat them down.
Brown is a legit dark horse, I think he can become champ with the right match ups. As a Brown fan, the guy who scares me the most in the top 10 is Demain Maia with his underrated takedowns and elite subs.
