Feiner/Duffy
This was from that Sports Illustrated article a few years back, I know it has been posted here in other threads, but just to add more to the brother-in-laws angle:
The Source, a sports-adviser service in Farmingdale, NY, owned by Stu Feiner, who also owns a few 900 call-in lines. Exhibit C is Feiner's brother-in-law, the aforementioned Kevin Duffy, perhaps the nation's most prominent adviser, who became famous for running ads that said, "I will go 7-0 for you today, absolutely free." Too bad "absolutely free" meant you first had to sign up for a month's service at $350. Then, if Duffy didn't go 7-0 in the first week, you got the next month free. Duffy, who operates out of Massapequa, Long Island, also claimed to be no worse than 75% right, ever. Yet when his picks were audited by the Sports Monitor of Oklahoma City, one of the rare legitimate monitors (among the dozens of such outfits that purport to keep tabs on the performance of tout services), he never fared better than 58.8% in any regular football season between 1985 and '88, and he sank as low as 39.7% for his college picks in '87. Eventually the Sports Monitor refused to monitor Duffy because of his "deceptive ad practices."
Feiner agreed to be monitored by SI for four weeks in September. To his credit, he unfailingly gave us his choices. To his discredit, Feiner went 19-32, a 37% win rate, and lost us an imaginary $6,210 based on $100 per unit. During that same period, we were anonymously calling Feiner's 800 number, where, curiously, he claimed to be cleaning up.
