I'm not sold on that one left hook putting Emmet into legitimate contention. Elkins is tough, well rounded and has cardio for days, but he's too reliant on grinding out opponents without really shining in any one area (that was a good win against Johnson, though). Ortega seems to just straight up pull wins out of his ass in fights he is losing sometimes, even though he keeps winning.
If Max gets by Frankie, there's no interesting fights for him at FW unless someone in the pack can get another dominant win over another top 5er to seal their deal.
IMO Frankie, Max and Aldo are leaps and bounds better than the rest of the top 10, and after Max and Frankie square off, they've exhausted all the fights possible with those three.
I'd be more interested in seeing the KZ fight the winner of Max/Edgar, although he probably needs a win before then. I'd pick KZ over Elkins, Ortega and Emmet.
