Were multi-year starting QBs isn’t good enough? Ohio State had 6 guys enter the portal today. Bama has had several announce previously who weren’t starters but guys who still accumulated non garbage time stats.
I’m not sure what your criteria are for good teams and starters. Top ten teams are losing multiple guys, some starters, some multi year starters.
Playoff teams maybe aren’t losing starters (yet at least), but teams playing in New Years Six bowls are losing players, plural, and some starters.
