They never could get out of regionals in the late 90s. In what was Blake Whitenake's last year as HC (95 or 96), they lost in the regional final to make go on the road and lose in substate play.

I would guess it would have been SP in 90 - 92 range they may have won the regions, but Wise was strong that time as well, so I am not sure when the last time a CD team would have won the regional title.
