What is with the lack of HD content on the NFL Network? I bought my first HD tv last October but did not sign up for Dish HD until this February. I spent the entire off season looking forward to the NFL Network in HD, and there's nothing there!! Playbook, Gameday, Total Access, all SD. The only HD content I've seen is the actual games (preseason and replay). Any idea when the NFL will invest in some HD equipment? It's not like they're short on cash.
