Milt Ahlerich has tendered his own retirement after serving as the NFL's vice president of security since 1996, league officials confirmed Friday. Ahlerich, who served in the FBI for 25 years before being hired by the league, spearheaded all of the major security matters that consistently confronted the NFL, including the Patriots' infamous Spygate scandal in 2007 and Favre's alleged dalliances with former Jets game hostess Jenn Sterger, which consumed his time during the second half of the 2010 season.
