WGR 550 Buffalo believes CB Crezdon Butler is still competing for a roster spot. Butler is currently expected to replace Stephon Gilmore (wrist surgery) at right cornerback for the first six weeks, but hasn't yet won the job. It would take a disastrous fourth preseason game for him to get released over T.J. Heath. UDFA Nickell Robey and Ron Brooks are battling for nickel duties.
