NEW YORK (AP) — As free agency began Tuesday, the NFL looked more like fantasy football.

Trades, anyone?

Monster deals sending Jimmy Graham to Seattle and Sam Bradford to Philadelphia stole the spotlight from free agent signings.

New Orleans agreed to send its star tight end to the Seahawks for center Max Unger, with draft picks changing hands. The Saints are to get a first-round pick, while Seattle receives a fourth-rounder.

That stunner was followed by Bradford, the injury-prone quarterback who barely has played the past two years (knee), going to Philadelphia for Nick Foles, who also comes off an injury-shortened season (collarbone). Bradford was the top overall draft pick in 2010.

Foles is the latest starter to depart Philadelphia. He joins two-time All-Pro running back LeSean McCoy, now in Buffalo, and Pro Bowl wide receiver Jeremy Maclin, headed for Kansas City, in going elsewhere.

Baltimore dealt nose tackle Haloti Ngata to Detroit, which is about to lose All-Pro defensive tackle Ndamukong Suh in free agency. Ngata, 31 and a five-time Pro Bowler, is due $8.5 million next season and has a $16 million salary cap figure.

The Bills confirmed acquiring McCoy for linebacker Kiko Alonso; McCoy also signed a contract extension for $40 million over five years.

Carolina released DeAngelo Williams, its career rushing leader.

Among official free agency moves early in the process were WR Brian Hartline to Cleveland; S Tyvon Branch to Kansas City; TE Owen Daniels to Denver; G Orlando Franklin to San Diego; CB Buster Skrine to the Jets; and QB Shaun Hill to Minnesota.
