Brandin Cooks has a new employer.  The veteran wide receiver signed to the Bills’ active roster on Tuesday.  Cooks, 32, was waived by the Saints over the weekend and cleared waivers Monday before joining the pass-catcher-needy Bills ahead of Week 13. He had reportedly requested to be released by New Orleans earlier this month.  A first-round pick by the Saints in 2014, the Bills will be the sixth team Cooks has played for during his 12-year NFL career. He’s made 729 receptions for 9,697 yards
