Wilder's speed/power very good, bt who else thinks he could improve as a finisher?

He answered a lot of questions, and now I honestly think he may be a force in the HW, and maybe a huge ppv fighter soon, but when he rocked Stiverne he looked as sloppy as ever lunging in wildly.
He should watch some Felix Trinidad tapes.
I believe if he had top level finishing skills he would have stopped Stiverne.
