Sexton vs Fury would be great but he could still have a decent career at domestic level. Anyone with definate class will beat him but guys of the level of Rogan he will have enough against. Sexton vs Sprott would be interesting too. Chisora should move upto euro level asap.
His head hurts because it has just hit the glass ceiling of his boxing career. Domestic level, maybe european (but that means jack **** these days). He could carry on and train harder and maybe get a European trap, or he could just carry on like he is in his comfort zone become a punching bag for young up and comers and retire with 12-15 losses on his record and a sore head.
I really never rated Sexton, even in the second fight with Rogan there was spurts of wilting and the feeling of one punch finishing it. He's just not that good, decent power but not much else. Chis is exciting, he's approaching his ceiling too though, European level I reckon.
He doesn't have decent power, which is a problem for him. He's not a big one-punch hitter and because his output is low and his stamina isn't the best, he won't go beyond domestic level. Sexton's main strengths are that he is technically fairly sound and has reasonably quick hands for a big guy but he lacks a bit of strength and power and he doesn't have the natural fitness he needs to go to the next level IMO. Chisora impressed me, i think he could go quite far. I think the main point though is that we actually saw a good heavyweight fight, two guys willing to bring it and throw a decent number of punches right through the fight. Both, in their own ways, can actually box a bit as well.
