Dumber Than Your Average Eagles Fan

I know Philadelphia Eagles fans aren't all that bright, but this Herbert Simpson fellow may well be the dumbest of all.

Feds yesterday busted a birdbrained Philadelphia man for allegedly trying to blackmail Giants Coach Tom Coughlin with false allegations of extramarital flings with two women.

Herbert Simpson, 30, was released on $10,000 bail and ordered to undergo a mental evaluation.

"The only thing I'll say is I received two different letters, I turned them over to the league authorities as was recommended, and it's in their hands," Coughlin said after practice yesterday. "That's all I can tell ya."

The letters went from Coughlin to NFL security officers, and then to the FBI, according to a league spokesman.

The Super Bowl-champion coach received letters on July 30 and 31, purportedly from two women who said they would out him for sleeping with them during a team trip to Philadelphia in December 2007, according to an affidavit written by FBI Special Agent Todd Berry.

Both letters were actually written by Simpson, who used the names of two former female co-workers, Berry wrote.

Investigators interviewed the women named in the letters, who said they knew nothing about them and had never met Coughlin. The women also identified the handwriting as belonging to Simpson, who they said had written threatening letters to others in the past, according to authorities.

"I conducted an interview with [Simpson] in which he confessed to sending the letters," Berry said.
