We actually (on paper) return a lot of experience next year. Like you said though, if there’s another big wave of players who transfer out, we are let again with a bunch of unknowns and will need to rely on kids who didn’t get time or newcomers.
With that said, there’s reason to believe the staff was/is coaching for their jobs this season. I’d imagine due to that, their main focus is getting the best players on the field as much as they can rather than development.
