The Buffalo Bills had two players start the majority of games at the second cornerback spot and both Levi Wallace and Josh Norman are not under contract for the 2021 season. Norman is an Unrestricted Free Agent and likely to command more money than Wallace, who is a Restricted Free Agent.
With Wallace, he’s been on minimum deals for his entire career as a former undrafted free agent. He was released in his rookie year, too, so that’s why he’s been signed to one-year deals in the interim. Buffalo was able to control Wallace as an Exclusive Rights Free Agent until this point.
