Kessler's chin is good... His stamina as well is fine, although he had some issues with it for one fight against Mundine, I dont think he got in the proper roadwork and training for that fight, and still won handily. Also JC was able to perform like that against Lacy because of his style, it's not like noone could ever beat him if he performs like that as you say... Lacy just kept coming forward the whole night throwing wild punches that were clear as day and easy to counter.. Kessler would definetly not do that, especially after being ringside for the fight. I think he has a good chance, and would certainly make for a hell of a test for Joe, if he boxes from the outside as much as possible. Kessler is really strong with a long reach and good, mechanical jab, plus he has a great straight right hand as well, which Lacy apparently hadn't even heard of when he fought JOe. hopefully this happens, great matchup.
