Honestly, as someone who used to watch Gameday religously... it's just not the same. I'll still watch it that first weekend, and also flip it on first thing on saturdays because the opening gets me in the mood for the day, but after that.... IDK.
I've been watching the Fox show more, because they actually cover more stuff. Also, while the BTN show isn't as "high quality" at least they talk about all the matchups. Gameday is 3 hours long, but only about 30 minutes of it is actually useful. Outside of the picks at the end of the show, the rest of it is all fluff pieces or focused on like 6 teams and the playoff.
