You can build small schools into powerful mid majors that can be nationally competitive. The SEC is tough in Phelan, so it will be a hard go for you, and it likely won’t happen in one recruiting cycle. But if you get them to the point where they are consistently winning their conference, you can raise your prestige to B- and up, at which point you can compete for just about any recruit with a favorable preference profile. For now, one big advantage will be recruits that want rebuild, so make sure not to miss local and regional guys with that preference, especially if they want playing time (assuming you are willing to promise it).
