I think a big part of the reason Ricky doesnt want to fight Witter is that Ricky is a gentleman who doesnt slag off any boxer, rather admires the talent in every opponent. Witter has been very offensive and rude, and so Ricky doesnt want him to get any money - simple as that. I know you will say well Maywaether has been rude also, well Mayweather brings more to the table than Witter LOL (by a million miles) so I guess Ricky feels he can overlook the shortcomings in his case!
