‘The Bills should not have allowed cornerback Jabari Greer test free agency. Greer was not the team’s top cornerback, but he had 17 passes defended and four interceptions the last two seasons. He emerged as a bona fide NFL starter last season, returning two interceptions for touchdowns. Not only did the Bills lose a good player — he signed with the Saints — but they left themselves with little leverage in negotiations next offseason when No. 1 corner Terrence McGee’s contract comes up. The team has no choice but to match his asking price, and McGee and his agent surely know it.’
