You're options are pretty limited without.
You can get someone's ISP sign in for the WatchESPN app (my guess is that this is against the ISP's terms of service for whoever shares the password).
You can go to sports bars and friends houses.
Other than that, I don't really see any legal options. You can stream BYUtv free. But that will give you the BYU-Savannah St. game live (all other football will be delayed).
