I'm looking for NFL lines from 2005/2006 and 2004/2005. I've been taking my NFL system and seeing how it would have done in past years, given that it was successful this past season. I have 3 seasons recorded so far and it still looks really good, but obviously the larger the sample size the better i feel. problem is, most places only go back 3 years with lines history. can anyone point me to where i can find lines for these 2 other seasons?
