Bro should have never left. I called it years ago when he first made the switch. I said he would do fine against the scrubs, but the moment he came up against ranked HWs with a physicality advantage over him plus some measure of athleticism and/or and grappling prowess, he would stall out. I think I even specifically mentioned dudes like Blaydes and Volkov.
Sure, 205ers might be a little faster and a little more technical overall. But I don't think the level of grappling talent at LHW is so much higher across the board to cancel out the fact that Jailton will be grappling against dudes he's liable to have a major size & strength advantage over.
He's #6 at HW at the moment, but that will probably drop soon. IMO, give him someone in the 9-15 range at 205 and let him work up.
It wasn't anything great, but it definitely wasn't awful either. Even when he's throwing hands his athleticism and explosiveness seem to translate and he fucked Spivac up with the first clean punch he landed not long ago. By the standards of a Heavyweight grappler, it could be worse.
That said, he is a bit one-dimensional with his attacks and definitely gun-shy. And yeah, he definitely seems to be one of those who gets stuck in one "mode" or another rather than blending his arts.
