I just can't rank Favre top 5 with his late game horrible decision making. Just go through this decade and look at his playoff games..
2001 vs. Rams in the Divisional Playoffs: 6 interceptions. Possibly the worst playoff performance of all time.
2003 vs. Eagles in the Divisional Playoffs: Brett Favre throws a game bomb 50 yards down the field and Brian Dawkins intercepts it and returns it and sets us up for a 40 yard fieldgoal or so attempt. Noone within 10 yards of the ball but Eagles.
2004 vs. Vikings Wild Card Playoffs: Brett Favre throws 4 interceptions against the Vikings. This was after he beat them twice in the regular season, at home.
2007 NFC Championship game vs. the Giants: Brett Favre throws an interception at the end of the 4th that was fumbled by McQuarters (luckily) and then he goes into OT and throws an interception to Webster to lose the championship game.
2008 vs. Dolphins final game of the regular season to get into the playoffs: Throws 3 interceptions and plays just down right awful.
This is just this decade..
All this decade.. from this article..

Just a small sample, since I am guessing you are too young to remember just how good Favre was in his prime.. or you're just basing all this BS off of last year when he played practically one-armed for half the season.
Say what you will about his retirement drama and his ego.. I agree.. the guys act was tired, but when it comes to greatness at that position? He's as good as all the greats, and in many cases.. was better.
