Well Almly, your argument is a poor argument, especially if you say you haven't watched football for the last 30 years.
I recently looked at 19 quarterbacks over the years (I'm sure I missed some) but the list comprised of:
Favre
Young
Montana
Marino
Elway
Manning
McNair
Kelly
Unitas
Aikman
Starr
Staubach
Tarkenton
Dawson
Bradshaw
Simms
Namath
Stabler
Fouts
Obviously, the only way to compare these guys is based on per game numbers and averages seeing the different time frames also produced different styles of play. I looked at the following:
Games played
TD/INT Ratio
TD/Game
INT/Game
QB Rating
INT/PASS ATTEMPTS (Obviously a qb who throws more is also suspectible to more int's so a percentage of pass attempts probably tells the best story)
Favre is 6th in games played (Again out of 19)
Favre is 4th in TD-INT Ratio
Favre is 1st in TD/Game
Favre is 11th in INT/Game (Ahead of the greats Peyton Manning, Johnny Unitas (He's won a few games), Dan Fouts
Favre is 5th in quarterback rating, which rates how effective a qb is
Faver is 7th in interceptions thrown when compared to how many passes he has thrown.
In comparing Favre to Elway, who you said was a great quarterback, Favre will be very close in games played after next season, has a better TD/INT Ratio, passed for a lot more TD/Game (1.79 to 1.28), Favre did throw more interceptions per game, has a better quarterback rating (86.9 to 79.9), and has basically thrown the same percentage of interceptions when compared to pass attempts.
Favre's teams have NEVER been below .500.
I don't understand the argument. If a great quarterback leads his teams to wins, then Favre has done that, by never having a below .500 season. If a great quarterback shows up every day, Favre has done that by not missing a game for 12-13 seasons. If a great quarterback wins Super Bowls, Favre has done that. If a great quarterback is somebody with great numbers, there aren't many that have better numbers than Favre, and most won't when he is done playing.
And people will point out Favre isn't the same quarterback he was many years ago. That's a bunch of bs too. The previous two years, his interception when compared to pass attempts was extremely low (2.9%). This year it was higher (4.1%). His quarterback rating over the last three years has been extremely high - 90.8, 85.6 and 94.1. His TD/Game and TD/INT Ratio have been outstanding the last three years. And his teams are 36-17 over the last three years. That's a 68% win percentage.
You take the good with the bad with Favre and there are plenty more goods than bads.
