Plaxico Burress' agent has informed the other 31 NFL teams his client might be available to play for them. Drew Rosenhaus, who has represented Burress since he signed with the Giants four years ago, sent an e-mail to all 32 teams earlier this week in which he indicated Burress could be acquired via trade, according to three people informed of the contents of the e-mail. Giants assistant general manager Kevin Abrams notified the rest of the league that the Giants had not authorized Rosenhaus to pursue trade scenarios on Burress' behalf, and that any inquiries about Burress' availability would constitute tampering.
