"Squabbling in public will eventually ruin football; there's no doubt it's hurting us already. Polls taken by Louis Harris - polls as valid as any political polls - indicate that very clearly"

Pete Rozelle is alerting that public squabbling within the football community will have a negative effect on the sport. He is referring to polls taken by Louis Harris, which show that the general public is already being turned off by the infighting. Rozelle is recommending that if the football community does not come together and put an end to the squabbling, it will have a detrimental impact on the sport. He is highlighting the credibility of the surveys taken by Louis Harris, which are as trusted as any political surveys. Rozelle is advising the football neighborhood to act and put an end to the general public bickering in order to protect the sport. He is alerting that if the squabbling continues, it will eventually destroy football.
