Well, Mueller scored 1 point riding against Rivera by having about 3 hours of riding time. Not a great point on your part.
Also, Lee is one of the most notoriously freakishly strong wrestlers in the country so he may as well be a huge 125. He may not actually be big, but he certainly feels like it to his opponents.
What I don't get is you acting like we haven't seen this match twice. It was tight 2 years ago. It is widely accepted that Rivera jumped levels since then. Rivera is one of the only guys in the country to score a takedown on Suriano. If your argument is Suriano is a tough match up for Rivera, it's only because Suriano is a tough match up for literally everybody because he's elite. There's nothing Suriano specifically does that gives Rivera trouble. He wrestles nothing like any of the guys you mentioned. Mueller out-slicked and rode Rivera, neither of which Suriano does. Glory gave Rivera trouble with attacks from space and wrist ties, more things that Suriano doesn't do.
They actually wrestle a really similar style, but Suriano is slightly better at it. If you said you'd pick Suriano every time, I'd agree, but that match will almost always be a 1-2 takedown affair, if for no other reason than all of Suriano's matches against top talent are 0-2 takedown affairs. Maybe you have a different definition of "kill" than me.
