I don't have a problem if Favre wants to keep playing but this guy is such a drama queen. It's like he retired but couldn't stand not having his name in the media all the time and people kissing his ass continuously so he had to come back because his ego is to big to not have that. Now we'll get more ESPN broadcasts of Favre playing with the Jets and it will be nothing but the commentators constantly showing 3 hours of man love for Favre while not even calling the action in the game or mentioning any other player on the field.
Some years ago, people thought Joe Montana should retire a 49er because he was old. But when he was with the Kansas City Chiefs, he did quite well and even helped take the team to the AFC Conference championship game. I think Favre has the ability to help take the Jets to the playoffs for at least three more years. I still don't see a superbowl of course, but it will be fun to see him outperform the young kid QBs who may have more on the ball physically, but not have the wisdom of Favre.
I like how he adjusted from a very fast pass to a favorite receiver and also running the ball, to a more varied form of arsenal where he would take his time and play more strategically. He can't fire a ball to a receiver among a bunch of defenders like he used to, but he has improved field vision and plays a lot more like Steve Young or Joe Montana in their heyday.
I think the Jets will do what the Broncos of the late '90s did with an old Elway. The Jets, like the late-90s Broncos, should develop an all around offense and rely more on running the ball. In later years, Elway did not pass as much but he still got two superbowl rings which eluded him in his three previous attempts when he was the most prolific passer.
The key to Favre being successful would be to not rely too much on his passing game and work the running game. What cannot be left to chance is injury at his age. Favre needs options and a new style of football in order to maximize who is he at his age.
That being said, he still may simply be too old to successfully compete anymore as a starting quarterback. In recent years, Brad Johnson started for Dallas at age 38 but lost the top spot. Favre can potentially be the oldest starting QB at 39 if he starts well and maintains in the first couple of months.
At the very least, Favre can be a backup and still be an asset. Testaverde set a record and won a game when he was 43 and I think Favre is the better player through a long career.
