He’s fought twice in the last 3 years & 6 in the preceding 3.
He achieved what he set out to, in replicating Buchanan, & has made a complete arse of it since, in similar fashion.
That he’s failed to attract a following, or major sponsorship, tells you all about his persona.
If he wants to resurrect his career, or cash out, then moving up & challenging Boots Ennis should be his only option; as opposed to a domestic rematch, at the same weight, where there’s zero at stake. Winning would add nothing to the view on the first fight & losing see him finished. Frittering his career away, in the process, just like his hero.
