Botha looks every bit of his age and has been in disgusting shape as of late.
He has 4 losses and a draw in his last 6. (his win came to a totally glass jawed Flo Simba)
A loss to a near 50yr old Holyfield, Grant who must of been 42-43-44 and a few guys he'd of destroyed a few years earlier. A few was debatable maybe.
Its difficult to say, hes at the tail end of his career and Sonny Bill Williams due to his name is a draw in Australia. I don't feel Botha is the type to lay down but with his age & the circumstances & such I wouldn't be too surprised if he got handed a nice final payday to find a spot on the canvas to lay down on.
If Botha is in shape and there too win, he shouldn't have much problem knocking Sonny Bill out at will but its a risky one. Me, personally, I'd avoid this one as tempting as it is to put a score down on The White buffalo.
