I'm sure it's a huge factor but I do also think there's professional motivation there tooMakes sense if that is why he is making a comeback 3 years out really bad shoulder injury must be for the money.
He was potentially a British boxing legend. The best cruiserweight since Holyfield bar none and like Evander he stepped up to also become the heavyweight champion battling bigger men in the process
There's not too many British boxers who did as well as he did yet now his memory is tarnish to the extent where he is a bit of s joke
He ran his mouth so much before the Wladimir fight that he just made himself look stupid when he failed to back any of his big talk up in the ring (when in truth losing to Wlad was far from something to be ashamed of and had he not talked so much prior to the fight he'd have probably been admired for going toe toe to with such a great champion and not being knocked out)
The toe excuse compounded issues plus the joke of an Audley fight and the two flopped fights against Fury - he became a joke figure and then did they whole I'm a celeb reality tv post fighting career
His boxing legacy is really not where it should be or indeed deserves to be what all he did achieve. So while there's a lot of money out there to make if indeed he is in need there is also a rather thin pool of heavyweight talent which presents him with a second opportunity to cement his legacy in a more positive light (like foreman made his legacy more than getting sparked in the DR Congo by coming back to destroy Michael Moorer)
