I watched the Pats/Saints game (actually DVRed and watched it later), and the PQ of Fox NFL HD coverage is still lacking compared to other networks. Although there is some variation in game-to-game quality on any given network, I would still rate NFL and college football HD picture quality by network as follows:
1. CBS-HD and HDNet (with their occasional Division III college game)
2. ESPN-HD
3. ABC-HD
4. Fox HD
