Very few position groups on the Houston Texans have as many question marks as the current cornerback room. While Houston was lucky to retain Bradley Roby this offseason, opposite him, covering the slot, and backing him up are a number of unknowns. Gareon Conley has a ton of potential, but has yet to capitalize on his first round draft status. Lonnie Johnson Jr. did his best to have the worst rookie season of a cornerback in Houston history last year—despite going 54th overall in the 2019 NFL Draft—earning a PFF grade of just 36.
