Even though Cleverly is a shadow, this current version of Jack would have battered him at any time regardless. It's incredible watching Jack improve so greatly, become so much faster, stronger and sharper as he gets older. They've got some good training "methods" in the Mayweather gym.

Cleverly was winded in the opening minute(s) which totally drained his confidence and output.

Jack-Kovalev would be some punchup.
