Ummm...no. Jerry Rice is the best WR ever and his last two seasons at 41 and 42 were bad. QB, Kicker, maybe punter can compete at 40. No other position has a chance.
Isn't Brady 0-1 in Super Bowls in his 40s? Sounds terrible to me.
Bud Adams told me the franchise he admired the most was the Kansas City Chiefs. Then he asked for more hookers and blow.
