Spurrier did take his 1992 team to the SECCG... but only after Tennessee dropped 3 straight games despite victories over both Florida and Georgia....
1992 SEC EAST
Florida 6-2
Georgia 6- 2
Tennessee 5- 3
South Carolina 3- 5
Vanderbilt 2- 6
Kentucky 2- 6
The bulk of Spurrier's success occurred between 1993-1996, when he won 4 straight SEC Championship Games. It just so happened that heisman winner Danny Wuerffel played all four of those seasons. It also did not hurt that ONLY 1 team (Tennessee) in the Eastern division was competitive (had a winning conference record) during that time.
1993 SEC EAST
Florida 7- 1
Tennessee 6- 1- 1
Kentucky 4- 4

Beginning in 1997, Florida lost their grip on the SEC EAST. For one, Wuerffel was gone, and a 3rd team in the SEC EAST became competitive again (Georgia)...
1997 SEC EAST
Tennessee 7- 1
Florida 6- 2
Georgia 6- 2
South Carolina 3- 5

Florida 7- 1
Georgia 6- 2
Kentucky 4- 4

South Carolina 0 -8
Spurrier did return to the SEC Championship, but not with the same results... losing to Alabama in 1999...
1999 SEC EAST
Florida 7- 1
Tennessee 6- 2
Georgia 5- 3
Kentucky 4- 4

He did win one more in 2000...
2000 SEC EAST
Florida 7- 1
Tennessee 5- 3
Georgia 5- 3
South Carolina 5- 3
Vanderbilt 1- 7
Kentucky 0 - 8
But in 2001, Spurrier lost out with one of his better teams....
2001 SEC EAST
Tennessee 7- 1
Florida 6- 2
South Carolina 5- 3
Georgia 5- 3
Kentucky 1- 7
Vanderbilt 0- 8
Since then....
2002 SEC EAST
Georgia 7- 1
Florida 6- 2
Tennessee 5- 3
Kentucky 3- 5
South Carolina 3- 5
Vanderbilt 0- 8
2003 SEC EAST
Georgia 6- 2
Tennessee 6- 2
Florida 6- 2
South Carolina 2- 6
Kentucky 1- 7
Vanderbilt 1- 7
2004 SEC EAST
Tennessee 7-1
Georgia 6-2
Florida 4-4
South Carolina 4-4
Kentucky 1- 7
Vanderbilt 1- 7
I don't see Tennessee, Georgia, or Florida dropping in competitiveness. If South Carolina becomes more competitive under Spurrier, he won't dominate. However, they might pull out an SEC Crown every once in a while.
