dude he got knocked out by kalib starnes and bill mahood.
thats two tko losses to guys that arent very good.
hes been subbed by patrick cote and various others and his only impessive win is over joe doerkson
leben knocks almost ever single opponent he fights out, has 2 losses and mcdonald has 7. mcdonald has recently been a doing well but hes an inconsistent fighter.
his only real advantage is that hes a huge mw, and will be bigger than leben.
