I don't mean overall it would never happen. And RAW, not a chance. I used to think not a chance with SmackDown! either but even in 2011 it wasn't as far apart as people think. SmackDown is usually about 0.8-0.9 ahead of Impact Wrestling in terms of weekly ratings. But TNA one week scored a 1.27 and SD! scored a 1.63 the very same week. That means there was less than 0.4 in the difference in ratings. Granted it was one week of the year but what I want to know is if people think it could happen?
I think it could, suppose SD! just happens to have a bad week with people tuning in (a big event is on the friday or something) and IW just happens to hit say a 1.5 (which I think they will at some point this year) then plausibly TNA may beat WWE in ratings one week!!!! I know it's SD! and it'd be taking a lot of luck into account but if this did happen it'd be a massive thing.
I know it's extremely unlikely but after my examination of the ratings and trends - it's not as unbelievable as you may think.
