In reply to Shani:
Benn wasn't terribly humble during his career - quite the rude party boy - never out of nightclubs and hanging out with footballers etc. Compared to Eubank he had an easier path to public recognition / getting the big fights - recognised as an amateur when he left the army, instantly was signed up by a gifted publicist / manager (Ambrose Mendy) - he was making waves and a known "face" from the start.
Eubank was sent off to New York as a kid and had to earn respect as a soft, lispy limey in the gyms there, returned to the UK as a complete unknown. Probably part explains (but doesn't really excuse) the ridiculous behaviour - anything to get sufficiently well known that existing big names couldn't duck him.
In reply to Phil Anderson:
Re Benn - he may have felt regret over McClellen's sad fate (he was a genuinely horrible man by all accounts but no-one deserves to end up like that) - but his feelings over boxing as a sport must still be pretty positive - given that he is an enthusiastic supporter of his son Conor's fledgling boxing career.
