Odds are the Buffalo Bills won’t name their next head coach until next month, after the National Football League playoffs are completed and there’s a full list of assistant coaches available to complement the ex-head coaches already on the market. Which leaves us plenty of time for speculation. First, let’s put the kibosh on one of the more popular names floating around. Not Jim Haslett — he’s not even worth discussing, as both he and New Orleans Saints management confirmed last week that there’s no out clause in his contract that would allow him to return to the team he played for in the 1970s and ’80s. The subject here is Jim Fassel, recently dispatched after six years at the helm of the New York Giants. He’s already interviewed with the Washington Redskins, and is reportedly being wooed by the Chicago Bears and Oakland Raiders as well. Which raises one question. Did the management of any of those teams watch the Giants play during the second half of the season?’
