I just finished Gunslinger, and it brought back all those bad memories of Brent retiring and then hemming and hawing and unretiring. Bad times, and the book did not give any insight that made Favre look any better or give at least some deeper understanding.

His brother made a good point: Brent needed to suck in order to convince himself it was time to retire; that's why that last awful year with Minny was so important. Favre was apparently emotionally incapable of going out on top.
