IMHO the problem with SC is that their 2 best shots at a NC are this year and next year. This year they graduate Gaines, Ibiam and Welch. Next year they graduate Mitchell, Sessions, Roy and Dozier.
Their 2015 recruiting class consists of 1 kid outside the top 100 and i'm not sure their 2016 class will contain any top 25 kids. Sure the core of Coates, White, Wilson and Cuevas is really good (plus Farmer, Davis, and the lone kid from 2015), probably a top 5 team, it is light years behind Tuck, Chong, Nurse, Williams, Butler, Collier, Boykin, Samuelson, Dangerfield, and then Irwin and Ekmark.
IF SC really lands no one of note in 2016, then she needs a blockbuster class in 2017 for A'ja's senior year. She's done a great job of keeping top SC talent from leaving the state, but she needs to be able to recruit nationally.
