I'm high on Tulsa too. I like them and root for them. But OU is just better. The last two times OU/Tulsa played it was like Varsity vs JV. Udoh and Jordan are nice players, but Warren, Tiny and TMG are MAA's. The talent gap is just too big.
I would have OU ranked about 20-25 and Tulsa just outside the top 25. I hope they have a great year though.
