Does anyone know what JM system in nfl that has never lost in history

I am trying to find out what his system is that he claims has never lost in the history of football.  I thought it was go against the super bowl winner in the first three games but he claims it won in week one and another bet was in week 2?????

I don't know what week 2 was. But according to my book in week 1 New Orleans lost the ATS as I had MIN +5.5.

I know it made me curious as he is really trying to sell it now.  I won't buy another from him but I can't see it being a great system if it only has one bet a year
