I'd go for Marciano's record if i were him..Dawson,Wright,Tarver and maybe Froch
he could get that all done in maybe 2 years and still pull it off i reckon.
He has always gone on about his legacy and he WILL fight at least one more then he'll be 3 away and earning silly money.
I'd love too see him go down as one of the greates to have ever graced the ring
