Buy is probably too harsh, but I couldn't tell you the last time I remember CPA getting a high profile transfer.
If your a 5A or 6A school that has legit aspirations of winning a title, you should be seeking out teams like Oakland, Alcoa, Maryville, Pearl-Cohn, Houston, Anderson County, Greeneville, Elizabethton, etc. The teams that consistently go 10-0 in the regular season only to get bumped in the playoffs early are usually the ones that could stand to upgrade their strength of schedule
Not gonna sit here and pretend Oakland doesn't benefit from some of the transfers they have gotten, but their Freshmen & MS teams haven't lost a game in 3 years. Building your program from the bottom up is how you make it last, even after coaches leave
