Povetkin is a very small heavyweight. He looked absolutely tiny next to Tyson Fury & Hughie Fury when they posed in New York recently and Wilder is of similar stature.
I think Wilder will counterpunch again as he did with Stiverne and break Povekin down and KO him late fairly nastily.
Povetkin has tonnes of heart and great technique, but he's a little guy and I honestly don't rate his movement and awkwardness as difficult as Szpilka who made Wilder look novice like for 3 rounds until he adjusted.
I think Povetkin poses a brave, well schooled but not particularly difficult problem for Wilder to solve.
He just needs to make sure to bring his own food and water with him
