The only thing I can think of is that I forgot the 2nd episode was on until 10 to 15 minutes into it, and only recognized that it was on because I saw this thread get bumped. I think a lot of people knew the season premiere was happening after the live fights so they were able to tune in based on that. Since I don't watch much on Spike TV, I didn't see any ads, and it took a week to remember that TUF is on Thursdays at 10 with no lead in. I think it was a blip caused by forgetfulness more than anything else. Now that people are "locked in" so to speak with the schedule I'd guess that the rest of the season should be between 1.5 - 1.9 with the finale about a half a point better on both ends.
