From various player quotes when they committed, it sounds like Pike makes it clear that no one gets promised minutes. I'm sure that would apply to Mulcahy and Massoud too. If McConnell, et al. want to keep their minutes after next year then they will put in the work.
FWIW, the OTB podcast with Carino indicated the staff was already surprised and impressed with both McConnell and Harper. Mathis is a 4* and projected to start, Kiss seems to have impressed and is a glue guy (again from Carino interview), and Geo is Geo. On top of that, Eugene, Issa and Carter will be seniors when Mulcahy comes in, with at least Eugene and Issa having a ton of experience. Young will be a red-shirt junior that was a highly touted 4* recruit...
This year may be rough with a young team but that roster in 2019-20 will be the best here in decades, at least on paper
