I know I'll be in the minority but I give Wilder a very legit chance. Liston had skills but he was hittable and Wilder is built to beat better boxers than him. Also, even though Liston was destructive, it isn't quite true that if he caught his opponent it would be all over. Tiny Eddie Machen survived with him
Wilder isn't without a puncher's chance, but he has an uphill battle considering he's totally inept with a jab in his face. He's also fragile and his history suggests he wouldn't handle Liston's power well. I think Liston blasts him as he did Williams.
Liston would blast him out in 1 and then straddle him and slowly.. SLOWLY.. DRIP hot diarrhea into his unconscious mouth.
