Yeah, for sure. Moreover, I think RDA is a better grappler than Luque and Chiesa also absolutely blanketed him for 2 rounds (rd 2 was close), and even when tired had enough to win the grappling in rd 3.
My thing with someone like Chiesa is that he understands what he is. The short time at the beginning of rounds when it's standing, he is very unlikely to engage and lead and leave himself open to be clippped. Not saying it can't happen (of course it can), but Mike's not gonna be looking to land anything significant. Luque loves to push forward and try to force a firefight. Mike will almost surely use that to get ahold of Luque and bully him back against the cage where the chain wrestling starts. And from there I just don't see how Luque stops the bigger, better grappler from having his way.
If Chiesa was a guy who had his skillset but fancied himself something he's not and randomly decided to stand for full rounds with clearly better strikers, no way am I this high on him here. But he's not.
Like Mariano Rivera was as a baseball pitcher. He basically threw one pitch that almost nobody could handle. He perfected that cutter and night in and night out he got guys out with it. He didn't try to throw a 100 mph four seam fastball or mix in big looping curveballs to show he could. He perfected one thing and dared you to beat it. That's how Chiesa fights. (Not a perfect analogy but you get the point).
Usman is a guy that can neutralize that grappling. Maybe Colby too. Possibly Edwards, Chimaev, etc. I'm not saying Mike is the best WW out there, he's not. He's gonna lose at 170 at some point for sure. I just don't think Luque is the guy to stop what Chiesa does though. I could be wrong.
