The fun thing about statistics is you can often twist and turn them to make whatever point you want to. For example, the above list of stats represent the ratings for all the seasons of TUF. While there’s obviously a pretty big rating slide from the 1st season to the latest season, but you could argue that the UFC stopped bleeding out and actually gained more viewers in the 18-34 age group than last season.
You can also argue that Season 4 was SO FUCKING BAD that it crippled TUF in a way that it has never been able to recover from. Or you can just go with your gut feeling and realize that the TUF formula is stale and needs a serious revamping … one I don’t think we’ll be seeing in Season 8.
