I have D*, but I'm planning to cancel, too. Last year I noticed how much college football there was on CBS, ABC, ESPN, ESPN2, Big 10 Network, CBS College Sports and the local RSN among others (most of them in HD). Seems like there ought to be enough to choose from, even if I don't sometimes get that one game I wanted to see most (and as a Verizon DSL customer I get ESPN360, too, and maybe some of those games on GamePlan will be there).
And with ESPNU now moved to the D* basic tier (i.e. not part of a premium sports package), there should be plenty of college football available without dropping a C-note on it.
