It's great that Brown is confident, but he needs to stay grounded in some reality. It's not like he's got a list of who's who in that win streak. More like a list of who's that. He's never accomplished Lawler's level of success and I don't believe he's nearly as devastating a striker as he is so he may want to shy away from those comments.
This is worse than the Bisping argument. Brown is even less deserving. Every ranked fighter above him should be in an uproar if he gets a title shot with one more win. The argument that some of those guys have a few losses or only a 1 or 2 fight win streak is irrelevant because they fight quality fighters. Give him any of those guys last 5 fights and Brown would have a considerably different record. His #6 ranking may be the softest ever.
