Sanders is faster but Parker has become a beefcake of a fighter. I very much like how he's fighting nowadays. If I can pick versions I'd take the lighter Ali-wannabe version of Sanders who was happy to use lateral movement and speed to outbox his opponents. Exchanging with Parker could be dangerous; he seems tougher and more savvy than ever nowadays.
Parker by decision. I think he can survive the early onslaught and win a decision. Would a Sanders stoppage win shock me? No. Sanders could stop most fighters, even someone as durable as Parker. Parker competitive UD.
Sanders by decision. I don’t totally buy that the current Parker would be any better at beating solid boxer movers than he was earlier.
Parker breaks through Corries non existent defense and lays him out. Too rugged ,too tough , too fast. Bad matchup for Sanders.
Corrie stops him, Parker has never in his life fought a faster fighter especially with atg power. Corrie finishes what Zhang started. I always thought Frank Sanchez would expose Parker despite not being nearly as proven due to speed and counter punching
