Cook's first client as a sports agent was
Brett Favre, after the two hit it off playing golf in Mississippi. Cook's next client was quarterback
Steve McNair. In 2001, Cook negotiated the
NFL's first $100 million contract, when Brett Favre signed a lifetime extension of his contract with the
Green Bay Packers. Some of Cook's notable clients have included
Calvin Johnson,
Randy Moss,
Marcedes Lewis,
Adalius Thomas,
Michael Turner,
Jerious Norwood,
Tony Scheffler,
Cam Newton, and
Russell Wilson. In 2014, Cook signed
Jadeveon Clowney and
Eric Ebron. Cook responded to these in an interview with
Sports Business Journal saying: "I heard I am trying to sell my business, I am not trying to sell my business. I don’t know who brings all these things up. I guess there are a lot of agents selling their businesses these days, or they are merging more than selling." Cook was at the center of Brett Favre's indecision on whether to retire during three straight NFL off-seasons from 2008 to 2010. In the summer of 2010, Favre mentioned to
Ed Werder of
ESPN that it was possible that he would need ankle surgery. Cook took exception to Favre's admission and was quoted in an interview in the August 2010 edition of ''
Men's Journal'' as saying: “Brett talked to goddamned Ed Werder at ESPN, says he needs ankle surgery. Now why did he do that? I’ve got (Minnesota Viking coach, Brad)
Childress calling. I’ve got reporters calling all damn morning. Goddammit, why does he have to be such a goddamned
drama queen? Play, don’t play, goddamn, people are getting sick of it. I’m getting sick of it! Why does he have to talk to these people? What good does it do? Ed Werder at ESPN! What’s he ever done for anybody other than say, ‘Look, look, Mommy, I got this first, ain’t I special?’ You got problems with
surgery, talk to your wife. Why talk to goddamned Ed Werder?” Favre would respond that Cook's comments were taken out of context, and that Cook was "joking around," but also added that "the lesson to be learned in all that is, I hate to even say it, is that you can't trust anybody." ==References==
