I don't think I'd go that far. Jay County will be far more competitive in the ACAC within a couple of years, but to go from 3 wins per year since joining the ACAC (1 in the past two years) to being too strong for the conference in 3 years is an exaggeration. The potential might be there eventually, but the conference is usually top heavy with strong teams recently from SA, AC and, a few years ago, Woodlan. Those 3 teams have had stretches of consistently winning lop-sided games in the conference.
Since Jay County joined the ACAC, here's how their 3 wins per season stack up with the top 4 teams in those years:
AC - 10 wins per year, 3 regional championships, 4 sectional championships
SA - Just under 8 wins per year, 1 state runner up, 2 regional championships, 5 sectional championships
Woodlan - 7 wins per year, 1 state runner up, 2 regional championships, 2 sectional championships
Bluffton - 5 wins per year, 7-8 wins per year the last 3 years
Jay County has the numbers, assuming Coach Zgunda can get them to come out, to eventually make its way to the top of couple teams in the conference, but it will take more than a great coach to get them to the point where they need to be promoted to a larger conference in 3 years.
