An interesting excerpt from the book " '59" by Gary and Maury Youmans, (page 141):
Val Pinchbeck (Syracuse Sports Information Director: "I used to go down to New York every Monday to the writer's luncheon. Occasionally I'd take Benny down but not every week. I'd go over to the Associated Press and they basically counted all the votes for the weekly poll. In those days everybody subscribing to the AP service got to vote. lo and behold, we found out that little radio stations in Mississippi or Florida or Texas, somewhere down there, would vote for the Southern teams and they'd leave out Syracuse, they'd leave out Southern Cal. in other words, those teams didn't get any additional votes, the didn't get ANY VOTES. So eventually they made up an internal decision that if somebody voting didn't at least cast a vote for the three major unbeaten teams in the top ten, they threw out the vote. That helped us in the polls as the season went on. The guys up North wouldn't do it, in other words nobody in Syracuse, or in Ithaca or in Rome would send in votes for Syracuse and leave out Southern teams."
We can be glad they threw out those votes in 1959.
