Yes, Sealey did beat Ryder at Super 32 in 2021 at 152. That weight class was won by Nicco Ruiz and featured Sealey, Ryder, Angelo Ferrari, Mitchell Mesenbrink among others.
You could be onto something with Cole Mirasola. If he plans to go heavyweight, he will have the path of least resistance for all the recruits. I put him last on my list because I think he's a tweener size wise and may struggle with the size of the heavyweights. I'm sure he will prove me wrong though...
