I think Quarry outboxes him in a competitive fight. Quarry was quite quick and he wouldn't just stand there. Kabayel's size advantage would pose some issues but Quarry was very good at handling punchers. Its guys quicker than himself who bothered Quarry and Kabayel is no speed demon. Quarry by a competitive UD. I think he is a little too quick and smart and won't stand there and let Kabayel work his body.
Kabayel can box, he isn’t just a pressure fighter, we seen that against Makhmudov, he just pressured in his previous 2 fights because he felt that was the better game plan to get the job done. Guys who could box gave Quarry the most issues, he prefers you to pressure him to give him counter punching opportunities, he doesn’t know how to force errors.
