ATLANTA – Dan Quinn never stopped believing he could turn things around in Atlanta.He won’t get the chance.With the Falcons mired at 0-5 for the first time since 1997, Quinn was fired as the team’s coach — just hours after a 23-16 loss to the Carolina Panthers.Longtime general manager Thomas Dimitroff was also dismissed.Quinn's five-plus seasons will be remembered for a Super Bowl meltdown at the end of the 2016 season, when the Falcons infamously squandered a 28-3 lead to Tom Brady's New England Patriots and became a national laughingstock — a stigma that lingers to this day.That ugly memory returned in force this season, when the Falcons became the first team in NFL history to blow fourth-quarter leads of at least 15 points in.
