Even if he does lose it will be age and/or weight-related rather than facing a better boxer - (unless someone truly sensational comes along at 160 in the next few months!!!)
Fighters? Nope. Mugabi was shot to ****. The one better fighter he actually beat was Julian Jackson, a glass jawed natural super welterweight who was much smaller than him. However G-Man got outboxed by two journeymen and got destroyed by Benn. You can stop using resume as an argument because it backfires this time.
