Speaking of Favre, let's face it: Aaron Rodgers would not be the quarterback he is without a little help from Brett Favre. Favre, and the legend he left behind, were two of the most important things in Rodgers' development as a quarterback.
The perception has always been that Favre's relationship with Rodgers was strictly professional, and, perhaps, for the most part it was. However, as Rodgers himself once stated about his time as a backup:
That was a valuable time, it really was. I really learned a lot about practice habits from him, and I think you realize as a young player that a lot of the time, the practice goes as the top player or top leader goes. Practice time is so vital to the success of the team, so he would every day bring energy and enthusiasm, and I learned a lot of important lessons like that.
Favre was responsible for developing Rodgers' leadership abilities, one of the most critical attributes of a successful quarterback. The fact that Favre refused to let Rodgers replace him also drove Rodgers to become the best quarterback that he could be, and when it was his time, he stepped up to the plate. In reality no one else would have been capable of replacing Favre as the Packers' QB except for Rodgers, who, because of his talent and character, was the perfect replacement for Favre.
