Sports Package Lineup

I'm thinking about dropping down from Preferred to Starter and I was wondering if there was a way to know exactly what channels come with the Sports Package? I've had the Sports Package for several years but I don't even know exactly what comes with it.

I understand that dropping from Preferred to Starter means I lose the MLB, NFL, NBA, & NHL Networks, along with ESPN News, ESPNU, and CBS Sports and some others but I was hoping that having the Sports Package would still allow me to retain these?

If there is a way to get a complete list that would be great. Thanks for any help. If Xfinity workers see this, my zip code is 37748.

Thank you
