‘Levi Wallace is the incumbent, basically. He had an fine rookie season in 2018 after going undrafted and began the 2019 season as the No. 2 corner. Although he broke up nine passes and snagged two picks, after a few games with uninspiring play midway through the season, Bills coaches decided to rotate Wallace and veteran Kevin Johnson — who’s now on the Browns. Wallace has to play more consistently to hang onto the job. And the Bills made a low-risk, potentially high-reward cornerback signing when Josh Norman was inked to a one-year deal in March. Of course, Norman rose to stardom in Carolina in McDermott’s defense but is now 31 years old coming off a career-worst season in 2019. These two will battle it out and play a decently large role in deciding the ceiling for Buffalo’s high-end defense.’
