Not so sure, particularly if McDonald was still here.Young would have started here.
Young and Freyler probably aren't suited to play either of the other safety positions. They could do it, but playing both probably limits what you can do. That position is very different from the other two S positions.
So you would have to be sure that he's going to beat out Freyler, because I think that's the only way he would've started. On the continuum between LB and CB skillset needs, the other two S positions need to be closer to CB skillsets. Young struggled in the passing game last year in the S position that demanded the least in the passing game by a significant margin. And I don't think Freyler would succeed in one of the other two safety spots either.
Are Young and Freyler better players than Verdon? I imagine so. But just because they are all S, doesn't mean the positions are the same.
The Clemson game was the most impressive performance by the ISU safeties playing in space, both in coverage and making tackles in space. The last time a Fr. on defense had a WOW game like Freyler had was Rose vs. Iowa.
