By what basis do you believe this?
A Few Names,
Vince Taylor - was very successful back in the day and both you and he have said he is in bad shape
Melvin Anthony has stated on PBW, not in good shape financially
Nasser has to sell clothes on his site/ebay
I am sure there are a more out there.
It's a problem across all sports/athletes....so many live in the now and don't prepare for the future....
