I don't know all the exact details, someone smarter and more useful can find the exact terms.

BUT

There will be a change I really like! If you lose your wild card game you are slotted something like20th-24th. Where you should be. Instead of your season record.

For instance the San Diego chargers made the playoffs but have the 16th pick. With the new structure they would be at least 4 spots lower.

it will affect the other playoff teams the same way just different slots.

Before wrapping up their annual spring meeting today, the NFL owners enacted a change in the draft process that will reseed the draft order from the 21st pick through the 30th depending upon how those teams finish in the postseason.

According to John Clayton of ESPN.com, the change passed unanimously and will first take place in 2010. With the new procedure, the team with the worst record and other teams that don’t make the playoffs will be ordered based on won-loss record.

As for wild-card losers, they will be seeded through No. 21 through No. 24 based on record and finishes.

Divisional round victors are going to be seeded at No. 25 through No. 28 with conference title game losers seeded No. 29 and No. 30, the Super Bowl runnerup seeded 31st and the Super Bowl champion still picking last in the draft.
