As quarterback Daunte Culpepper waits for the phone to do something other than sit there and stare at him, his chances of returning to the Raiders apparently are shrinking.

The Raiders recently have signed quarterbacks Erik Meyer and Jeff Otis, giving them four arms on the roster as offseason camps approach.

Four is the magic number for most teams when it comes to training camps and the preseason.  Then again, neither Meyer nor Otis have played in a regular-season game.  So it’s possible that they’ll be competing against each other in the short term, and that one of them will get the boot before too long.

Though Culpepper still shows up on the team’s official online roster, the transactions page on the Raiders’ web site makes it clear that Culpepper, who played under a one-year deal in 2007, has not be re-signed.

No one has shown any interest in Culpepper.  In fact, the only time his name has been mentioned came on the first weekend of free agency, when the Randy Moss camp, in an obvious effort to put pressure on the Patriots, leaked that Moss had reached out to Culpepper about possibly reuniting on the same team.
