A 12-year NFL career (1974-85), a three-year run as NFLPA president (1984-86) and a sophisticated understanding of NFL economics have helped make Tom Condon the most influential agent around. He's negotiated some of the largest deals in NFL history, including the Manning Brothers' contracts, which together total nearly $200 million. Condon has approximately 80 clients, with quarterbacks Drew Brees, Tony Romo, Matthew Stafford, Matt Ryan among his most prominent. Who did Elvis Dumervil call after his contract snafu with the Broncos? Condon, who promptly negotiated a $35 million deal for the linebacker. Not all of Condon's clients are easy sells. One of his most impressive feats was preventing Manti Te'o from falling in the draft. Despite the embarrassing catfishing scandal and a poor showing at the NFL combine, Te'o was an early second- round pick of the Chargers. Think his agent had anything to do with it?
