Favre Trade Shakes Up AFC East

The Jets trade for Brett Favre shakes up the AFC East. The Jets figured to be

better than last year's 4-12 record. They spent $140 million on free agents, but still had a question at quarterback. The don't have as big a question now. I don't
agree with the immediate reaction that the Jets are a playoff team. That means the Jets will be 6 wins better. Not likely. They still have too many questions, and some of them related to Favre. Can he still do it at 39 years old? I know he did last year, but when you hit that age, each year is an unknown. The Jets are not strong at receiver. Their line is better with Alan Faneca, but not great. How quickly will Favre get comfortable in offense?
But now matter how many they win, the trade effects the Bills because the Jets ARE better. That means beating them twice like last year won't be as easy. I still think the Bills are the 2nd best AFC East team, but the gap isn't as wide as it was on Wednesday. Maybe it helps the Bills obecause hopefully Favre can figure out a way to knock off the Patriots.
Bottom line, Favre is an upgrade over Pennington/Clemens, and anything that makes a divisional opponent better is a concern for the Bills.
