Agent Drew Rosenhaus isn’t making a ton of friends lately with the way he’s decided to make his clients available for trades, without speaking to the teams first.

Case in point:

Plaxico BurressDrew Rosenhaus, who has represented (Plaxico) 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. The people, who requested anonymity because the e-mail was not to be discussed publicly, said it was a list of Rosenhaus’ free-agent and draft-eligible clients as well as three players he deemed trade-able.

All three are wide receivers: the Cardinals’ Anquan Boldin, the Bengals’ Chad Johnson and Burress.

But according to one of the people familiar with the situation — a member of one team’s front office who was on Rosenhaus’ list of recipients — the Giants had plenty to say earlier this week. 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.

Another person informed of the situation said Rosenhaus sent out another e-mail yesterday in which he clarified he doesn’t have permission to seek a trade for any of the three clients he listed.

This numb nut just decided to send out a mass e-mail letting other teams know that Burress, Boldin and Ocho Cinco were available without talking to their respective teams first. Brilliant! These power agents really do feel like they can do whatever they want.
