That for the sure, plus the middle of the show wasn't very appealing. Nyla v. Ruby lost a lot of viewers, as did the House of Black match (although Black generally draws good quarters). Punk-MJF did grow viewers but they started from a low point. From a ratings perspective, it was probably a good thing they went 45 minutes and not 15.
I think we had also forgotten just how popular and good of a ratings draw Moxley is. Granted, a lot is the lead-in factor, but even on Rampage, his quarters have done really well. I expect to see the Mox-Danielson program draw great numbers too.
