Brett Favre
Favre was one of the best quarterbacks of his generation and his opinion carried a lot of weight in the Packers’ locker room. The signal-caller criticized teammate Javon Walker after the receiver missed the start of training camp in 2005. He had a harsh reaction to Walker’s situation and told the franchise not to bow down.
“When his agent tells him not to worry about what his teammates think and all that stuff, I’d tell him I’ve been around a long time and that stuff will come back to haunt you.” Ironically, Favre had several contract disputes with the Packers and retired multiple times (via Las Vegas Sun).
