Schneider and Jack Morris both very successful coaches and their records prove that out. One interesting similarity is that they both benefitted from a substantially larger base of actual and potential football talent that did not bump their school up to a larger school competitve class.
Schneider essentially had all of the Campbell County Catholic football talent but not the numbers counting against him because a sizable amount of the nonfootball students in the central and especially southern end of county would have attended Brossart. Would the perception of Newport Central Catholic be different if the name of the school was Campbell County Catholic which more accurately reflected its football team during the Schneider era as I expect that the vast majority of the football talent over that time was from the rest of the county (Ft. Thomas, Highland Heights, Southgate, Cold Spring, Alexandria, etc. and not Newport).
Similarly, Morris coached at Mayfield at a time when the Graves County school system was not consolidated and consisted of 7 or 8 small schools none of which fielded a football team so if you lived in Graves County and wanted to play football Mayfield was the only game in town (er, the county). So it similarly was able to pull football talent from a 6A size talent pool base while being able to play primarily in the smallest (or occasionally, next to smallest) class.
Again, both successful coaches and nothing improper about taking advantage of the beneficial circumstances applicable to their situation but both enjoyed meaningful competitive advantages that contributed significantly to their success. And because tradition and legacy of players (sons, grandsons and other family members) is so much more important in football than most sports because of the need for both elite talent and numbers the advantage built over that earlier period has helped sustain continuing success in both those programs.
Perhaps some other coaches listed above have enjoyed this type or similar advantages (other discussions on BGP over the years have referenced drawing talent from other nearby states or other areas not part of the school district ) and as also discussed on BGP and other message boards over the years ad nauseum probably most of the coaches have enjoyed some type of competitive advantage (private school, exceptional community support, etc.) that have been an important contributing factor in their success but that does not diminish the accomplishments of any of them but does perhaps add some helpful perspective.
