Don Majkowski
Before the legend of Brett Favre even began in Green Bay, there was another star quarterback in northeast Wisconsin; that would Don Majkowski, “the Majik Man” himself. In 1989, Majkowski threw for 4,318 yards, leading the NFL en route to a Pro Bowl selection and being named Second-team All-Pro. But just 10 games into the ensuing season, the “Majik” was gone.
He suffered a season-ending shoulder injury in 1991 and was eventually replaced as the starter. When he did make an appearance in the 1992 season, he suffered another season-ending injury that made way for Favre to take over the job. Needless to say, Favre had the starting job in Green Bay for a long time after that, leading Majkowski to become a backup elsewhere for a few more seasons.
