With Gall, people seem to mostly remember 2 fights. The shitshow vs Diego where Gall was literally in the middle of kidney failure (not the BS excuse after the fact type deal---he was in the hospital a WEEK after that fight because his kidneys were shutting down) and the fight with Perry because Gall got outgrappled.
The Sanchez fight is barely worth talking about. If you rewatch it, Gall looked like a straight up zombie before the end of rd 1. Dude should NOT have been in that cage, he should have been in the ICU.
The criticism from the Perry fight is fair to a degree, but there's other takeaways from that fight. Standing, Gall actually may have gotten the better of it. He landed a lot of good shots on Perry (the same Perry who went toe to toe in a war with Luque) and Gall's success standing was potentially part of the reason that Perry surprisingly went to his grappling. Also, Perry showed himself to be maybe a bit of an underrated grappler IF he can get top position. He's mostly useless off his back, but he was so much physically stronger than Gall that any technical advantages Gall had were neutralized by Perry's strength.
I think Morono is decent but nothing special. Pretty good all around fighter but does nothing exceedingly well. Paying -2xx on him vs a guy with world class grappling and submission skills who's also tough and durable as hell...can't imagine doing it.
