Under the old rules and transfer system, that was true, yes. But with the new world of today’s college football, I think they’d be a small increase on some players returning.
It obviously depends on the “why” on why they entered the portal. And for the Utes, this off-season would likely be different than most, if only for the coaching changes and hires and bringing some of their own preferred players with them. So, just saying that makes this off-season a bigger “one off” with all the different variables going on.
