ORCHARD PARK, N.Y. -- The Buffalo Bills' chances of trading for New England quarterback Drew Bledsoe are diminishing.

"I'm not overly optimistic that it's going to get done," Bills president Tom Donahoe told Buffalo radio station WNSA on Friday. "I still don't have the sense that they really want to do this, particularly with us. And that may be part of the hangup."

The Bills and Patriots are AFC East Division rivals, meaning Bledsoe would face his former team twice each season if dealt to Buffalo.

Without disclosing the offers that have been made, Donahoe suggested that New England is asking for too much in return.

"We'd like to do it, but we don't want to do something that we feel jeopardizes our team or our organization long term," Donahoe said. "There are other quarterbacks out there besides Drew Bledsoe. They're veteran quarterbacks. We have a draft tomorrow, and there'll be good prospects available there."

The Bills have 11 picks in this weekend's draft, including the No. 4 selection, and four picks spread over the first three rounds.

Bills spokesman Scott Berchtold told The Associated Press on Friday that there had been no new developments in the negotiations with the Patriots.

The Bills have spent the last month pursuing Bledsoe, the three-time Pro Bowl selection who lost his starting job due to injury to eventual Super Bowl MVP Tom Brady last season. Bledsoe has indicated that he doesn't want to return to play for the Patriots if he's not given an opportunity to win his starting job back.
