Who is the next american Heavyweight Hope?

Jennings and Wilder are close to the same quality.

I saw more boxing than brawling from Wilder vs Stiverne. I wasn't expecting that too much. Wilder made a big tactical mistake throwing a longe range right-hand uppercut but Stiverne couldn't make him pay for it. Try that against Klitschko and he'll be laid out on the canvas.
