But I had forgotten about the backup QB who preserved Miami Dolphins perfect season in 1972. It remains the only unbeaten season in NFL history. Earl Morrall, (an old journeyman QB like McCown, only older) came off the bench that year and started 9 games when Griese broke his ankle. Miami won all 9 of those games, and then Griese returned to lead the team to a Super Bowl win. Morrall played 21 seasons in the NFL. He died today at age 79. Hope Trestman has a solid #2 this season.
