So, you can use Bracketmatix.com to see multiple different brackets and to see where our average is. I personally like using the site to see where the top 5 brackets (go to their rankings, you'll find the top 5 brackets over a 5 year average).
Based on that, Bracketmatrix average has OU as an 8 seed (not sure how updated it is)
Top 5 bracket rankings
1. BV updated 3/4/18: 9 seed
2. Athletic updated 3/2/18: 7 seed
3. Syracusefan7 updated 3/4/18: 9 seed
4. HoopsHD updated 3/4/18: 8 seed
5. JabeBlog Updated 3/3/18: 10 seed
So based on these alone, it seems like OU is around the 9 seed line, fairly solidly in.
