They were always overrated and carried by the talent. Jackson/Wink fighters have HORRIBLE fundamentals. Too much unorthodox, flashy, spinning shit, gimmicks kicks etc. Those dorks dont have a consistent system. Technique got a bit better with Brandon Gibson but still far below the true top gyms/coaching staffs.
Jackson/Wink fighters cant even jab. Bones, Condit, Holm (a fucking former pro boxing champ and top 10 alltime female boxer), Hashad, Dodson, Guida, Kennedy, Bagautinov, Diego etc. They had stinky boxing defense, just downright horrible and clueless in midrange b/c their fundamentals are ass cheeks. Their footwork is mostly awful, bouncing around, unnecessary steps, not sound defensively, inefficient etc. Only exception is Cub who trained with Joel Diaz for his boxing.
Frank Murr had shit boxing technique there, left to train with that Freddie Roach protege and dude was throwing nice jabs, hooking off it and showed by far the best boxing technique of his career. Erik Perez looked better than ever training with Alliance after moving too. Jackson/Wink fighters historically rely on cardio, athleticism, volume, durability etc. for success. Condits insane chin and cardio has seen him win and come back from many fights he wouldve lost if his physical attributes there werent so great. Dodsons athleticism and speed made up for a lack of craft outside of counterpunching which hes good at, which is why he has so many fights where he does jack shit and looks terrible (Makovsky, Elliot, Runes etc). Their physical strengths carry them when their technique consistently falters.
