I know this was discussed before but don't remember if anything definitive came out of it. Looking at the Bio for Quinn Kuntz, it shows the 20-21 season, which was the covid year, it states, "Did not play (Redshirt Season)." Just being on the roster, even if you did not play in any games that season, would allow you the extra covid year automatically. By not playing in any of the games, you could redshirt like any other year. This would give you 2 additional years for the 1 covid year. Don't know if this makes sense or not, but that could be an explanation for being eligible this year.
