re: Has LSU passed Tennessee in terms of Tradition.

LSU has run away with the Fulmer Cup. That used to be Tennessee's thing, hence its name.

I don't think its particularly close. By my metric that I post each year following the end of a season, here's where the SEC programs rank in terms of Program Strength (goes back to 1936 but gives bonus points for accomplishments that are more recent):

1. Alabama- 1,271
2. Ohio State- 979
3. Oklahoma- 970
4. Notre Dame- 844
5. USC- 787
6. Michigan- 712
7. Nebraska- 681
8. LSU- 657
9. Texas- 644
10. Florida St.- 585
11. Miami- 582
12. Florida- 581
13. Penn St.- 553
14. Georgia- 503
15. Clemson- 502
16. Tennessee- 499
17. Auburn- 487
18. Michigan St.- 347
19. UCLA- 336
20. Texas A&M- 303
21. Washington- 295
22. Wisconsin- 286
23. Arkansas- 267
24. Oregon- 254
25. TCU- 246

LSU is now solidly #2 in the league. Tennessee will likely fall behind Auburn within the next few years assuming Harsin doesn't tank AU's program.

Here is where Tennessee ranked nationally at the conclusion of each decade, going back to the 1950s:

1959- #6 (top SEC program)
1969- #10 (#2 in SEC)
1979- #9 (#2 in SEC)
1989- #13 (#2 in SEC)
1999- #10 (#2 in SEC)
2009- #12 (#3 in SEC)
2019- #14 (#4 in SEC)

And now after 2020, they've fallen to #16 and fifth in the SEC.
