Whether you want to admit it or not, recruiting at an elite level is critical in competing for and winning a national championship. Yes, coaching matters, too. So does player development. We can be nuanced and honest enough to understand there's not one factor that overrides all else when it comes to putting together a championship-caliber team. If you want to head down that road, lucky breaks play a role, too.
However, combining individual factors like those can't lead to blanket statements like "recruiting stars don't matter." Of course they do. The star system is an inexact science, but it matters all the same.
