I think the heavyweight division is weak enough for him to be a top contender in the future. I don't think he's got a high ring IQ and his one punch power isn't great. His positives are his combinations are decent and his movement is quite good. His main negative is he second guesses his opponent when he has them on the ropes. Sanchez vs Ajagba would be a good measuring stick for both.
You can't get bulldozed by Kabayel and be World level, you just can't. Sanchez didn't have an injury, he just has no heart. feed him to Jalolov. I still like the cuban style though I will keep watching
