Bully the Bully
Following the blueprint set by Marcos Maidana against Mayweather in 2014—never mind that it ultimately didn't work—McGregor should fight rough, wild and aggressive.
Make no mistake: McGregor has serious punching power. He'll want to connect on a clean left hook, but that won't be easy against arguably the best defensive boxer in history.
Mayweather's hands are known to be fragile; he's broken them in the ring before. If that happens again, and early, things could get more interesting.
