I moved away from Henry Co several years ago but have kept up with the program pretty well.
The facts are this. After realignment, they are in a region with Clarksville Northeast, Clarksville Northwest, Kenwood, Kirkwood, and Dickson County. Nothing against any of those schools, but that's basically a guaranteed region championship for Henry County every year. And their main obstacle from region 8 just moved up to 6A. Nothing is a sure thing, but that's a fairly straightforward path to the semifinals. They have a student body of 1300+ so their general talent level is a lot more consistent than the smaller schools that are more typical of West TN. Not to mention their community support is among the best in the state.
1A-3A is also a bloodbath in West TN. Outside of Shelby County, Henry County is absolutely one of the top one or two jobs in West TN. I can't imagine having to teach (probably PE or Wellness? Give me a break) will deter many applicants.
