The 2000 talk got me thinking about the WBL of old and man were 1989-2004 REALLY good and REALLY fun. Just look at the number of Final Four teams. Pre 89: St Marys 77, 78, Celina's runner up in 83.
Post 04: OG 09, Elida and Kenton (runner up) in 11, Kenton 13 and 14, St. Marys 18
From 89-2004:
89- Bath
90- St Marys (championship)
92- St Marys (championship), Bath
93- St Marys (championship)
95- Celina
97- Defiance (championship)
98- Celina
2000- Van Wert (runner up)
01- Kenton (championship)
02- Kenton (championship)

16 seasons, 6 schools combining for 13 regional titles, 6 state titles, and 3 title game losses. Compared to 9 regional titles and 2 title games before and after.
I'll say that an expanded playoffs likely helps through the 70s and 80s, but around 2005 the league just fell off and hasn't (probably won't?) bounce back since. I'm glad my schools years coincided not only with the best years the league has seen, but the glory days of Defiance football. It was a lot of fun to follow every week and outside of some horrible Elida and Shawnee teams of early 2000s there wasn't an easy game on the schedule.
