I don't think the Jets should be nearly up there with Oak and Tenn. Don't forget that two years ago, they were a game away from the AFC Championship and on the rise. Then the wheels came off, but that wasn't management errors, but mainly injuries. I'd say the main gaffes were giving Chad all that dough prematurely (and maybe the drafting of Nugent) but we'll see how that goes.
Mangini and Tannenbaum seem to have the team headed in the right direction, even if it takes a few years to climb back up.
If we want to use that argument, Oakland was in serious contention after some brilliant management moves. They brought in Rich Gannon, dirt cheap. They brought in Charlie Garner, dirt cheap. They brought in Jerry Rice when everyone knew he was washed up and he went to Pro Bowls as a Raider. They rolled the dice on the young, unheard of, Jon Gruden. All of these things happened within the last six years. Rich Gannon got hurt and the Raiders went from superbowl game to 4-12. That was only a couple of years ago. They were in striking distance of three superbowls in the last six years. Baltimore beat them on ONE play of 97 yards to Shannon Sharpe and went on to win the superbowl. Then they go to a superbowl and as fate would have it, Jon Gruden was the opposing coach. He was in Oakland's huddle the whole game, and don't even get me started on the TUCK game when New England went on to win their first Superbowl.
Drafting Robert Gallery was the consensus move. Nobody can fault them for that. I am on the fence about bringing in Randy Moss and Warren Sapp, but still not evidence of
worst management moves. Aaron Brooks and Jeff George coupled with the hiring of Bed N' Breakfast boy are pretty much the three reasons that I still vote for Oakland, but let's not pretend the Jets, Titans, or a few of the other teams mentioned are above reproach.
