the thing is if Asukura really does manage to cancel his grappling, Pantoja becomes very beatable, seems he's relied too much on his back packing. Almost lost to Erceg who's not as seasoned as Asukura, and Moreno and Royval just didn't have the grappling base to stop him. I dont have enough footage yet to see how good his grappling defense is, it's hard to find. Pantoja has a solid chin but he's got average boxing defense , very hittable to punches. I would not be shocked if we witness an upset where he got wreckless and got stopped early. Just looking at the strike stats, Royval Moreno and Erceg landed a combine 370 significant strikes.
This has some elements of the fight between Patricio Pitbull vs Chihiro Suzuki.
Pitbull came in underestimated his opponent , also had no familiarity with japanese fighters and got koed. And at the time Pitbull had never been koed before, only a leg injury.
Edit: i should back track Asukura doesn't have those lethal heavy hands he might need to pull it off.
