i was trying to figure that at as well, in south florida you know there will be at least 6 games on regular t.v. - the 2 miami, thanksgiving, and the 3 monday nights. chances are at least two more will be on.
so banking on that i called direct tv and said i wanted downgrade my premium package w/out mentioning sunday ticket, the lady on the phone figured out thru different discounts for me to save $40 per month for 6 months. i figure at that point sunday ticket only costs me $10 per month for 6 months.
now watch, at least 12 games televised!!! Still worth it to have though, as the sunday ticket is a lot cheaper than a d.u.i.
