He made it where nobody will ever mention Iron battle again. In fact I could see some revisionist history happening and people calling his Solomon performance classic.
He completely validated the point he was making on Twitter and everywhere else after the Solomon battle. He forms his rounds to fit his opponent and breaks them down. The Solomon battle suffered in quality because he didn't have many great angles and it was too long, but he still had a clear victory. Even if the battle was terrible, a lot of that was because he had to spread it over 25 minutes and there isn't much ammo to hit Iron with.
I thought he got lucky then because Solomon was so bad, but it's clear he'll break down any opponent he's in there with. Maybe it's reactionary, but I don't think anyone except Charlie Clips has a chance to clearly beat him, because Clips doesn't ever seem to get rattled, can keep up with any style, be lyrical, and clown Mook at the same time. I even think Mook would destroy Math and turn the whole gun/staples situation against him and body him, and that's without the Dizaster angle.
I read some people call for Hollow vs. Mook on Twitter, but I'd take Mook there. I can't say Hollow, because he'd probably drop the ball in the first, take some weird angles that won't work, and end up down 2-0 before he realizes it. And that's coming from a Big fan of Hollow. He's got a lot to prove against Clips.
