UT obviously has a better program historically than Kentucky. But it is very doubtful UT will ever dominate Kentucky again like they did in the Majors- Fulmer era. Kentucky is legitimately better now and series will be much more competitive for the foreseeable future, imo.
Tennessee is 10-3 against them since Fulmer was fired, so they haven't exactly been competitive since then. The worst coaches to ever walk the sideline in Orange and White have winning records vs them. They are currently not as bad as normal, because their normal is 3-9. They were 6-0 with a win over Florida in 2018 as well but got stomped by Georgia and a sub .500 Tennessee team with JG at QB.
