QB rating is a bogus stat especially when you count all the passes that Favre threw right at defenders that were dropped. Favre could have easily increased his INT total by 5-10 INTs.
Farve had a 92.3 QB rating against San Deigo because he had a spectacular 4th quarter completing 14 of 17 passes for 2 TDs and no INTs. Granted, the game was out of reach for the Jets and the Chargers were playing a loose defense by that point (it was 38-14 at the end of the third quarter and the game ended with a 48-29 final). His first three quarters though, he was 16 for 25 with 1 TD and 2 INTs.
Favre had a high rating for the Cardinals' game, but that was because he had six TDs and four of those six were on drives started on the Cards side of the field and two of those drives were for less than 40 yards. Favre actually had three other possessions that began on the Cards side of the field and only had 6 points to show for it. Granted one was at the end of the half and only had time for one throw and then was forced to kick a field goal.
The first Miami game, most people agree that he was not nearly as good as his numbers and nearly had a really costly INT and only had a good rating because he had 2 TDs and no INTs.
You are overstating Favre's season. He was leading the league in INTs before his injury. He was still the same Favre from 2005 and 2006 who gambled and was easily pressured into making bad decisions. He had flashes at greatness, but Favre did an excellent job to keep his team AND the opponents in the game for most of the season.
Every time someone doesn't like what the passer rating says about a player, they call it a bogus stat. It's not. It's a compilation that has its strengths and weaknesses.
As for overstating his season, I'm not doing that by any stretch of the imagination. You keep tossing out the "only" arguments as if they mean something. Well New England "only" lost one game two seasons ago.
Look, I get that you don't like Favre. That doesn't mean that you should chuck all common sense and rationality away, though. The Jets were 8-3 and had just beaten the (at the time) best team in the NFL. Rather than ignoring that sort of thing, you should accept it and wonder what it might mean for next season if the guy comes back.
Was he really starting to get in synch with the offense, or was the 3 game stretch a fluke?
Can the Jets bring in better receivers to help?
Will that offensive line get better, or just older?
Will the extra year of age mean he becomes less effective?
Will his having a year with the offense mean he's more effective?
Will the new coaching staff help or hinder his game?
Will his injury have healed enough for him to play well?
He's never missed a game, but is father time finally going to change that?
Are the Jets really a legitimate challenger to the Patriots if Favre plays well?
etc....
These are important questions for fans and opponents alike, and ignoring them because you don't like Favre, and want to get a few more digs in at him, is just silly.
