I think we need some further info regarding choice of ring entrance costumes to make a decision on this one.
Lewis would have to take Wilder lightly, show up like he did vs the first Rahman fight, unfocused and under prepared and then Wilder has a punchers chance. But if we're walking about a properly prepared Lewis, then it goes down much like the Grant fight, he manhandles Wilder, beats him up and KO's him early.
I voted Wilder on points, but only because the OP went to the trouble of including that option and it would be a pity to remain unused....
Wilder would not be able to get at lewis Lewis would win on points unamonously but it would not be a very interesting fight
I think if Lewis tries to just box Wilder to a decision he gets KOed, but if he goes for the ko he probably stops Wilder around the 5th
