#1. Keith Lee

Few NXT Superstars will be able to get in the ring with Brock Lesnar. However, a man who seems to be inevitably headed for a clash against Lesnar is Keith Lee. At 6'2 and 350 lbs, he truly represents the evolution of "big men" in wrestling.
We've seen many iconic "Big men" over the years, but none of them had the athletic prowess of the NXT North American Champion. He's had two major appearances on the main roster so far - one in Survivor Series and the other at the Royal Rumble 2020.
At Survivor Series, he took Team NXT until the end before falling short to Roman Reigns. After the match, he got a fist bump from The Big Dog - a huge endorsement. He even went face-to-face with Brock Lesnar at the Royal Rumble. While he was eliminated, he posed a big threat to Lesnar.
It's clear that WWE has big plans for him and we can see a WrestleMania clash between Lee and Lesnar someday.
