If given my druthers, I’d rather have 4th year OC Getsy coaching this team than 2nd year Getsy. I don’t see how that’s controversial. I don’t WANT him in either scenario, but I’d rather have the more experienced version if I “hafta.”
No one is arguing the point you're trying to make here. Of course 'experience counts'.
But if Getsy is so bad that
it's not even fair to evaluate Justin Fields' play, if you're willing to use Getsy being a bad OC as an excuse for Fields ALL SEASON in his third year as a starter, it's crazy to say it's not an equally valid excuse if Caleb Williams plays poorly as a rookie.
If you think Getsy is a big part of why Fields hasn't been that good as a passer, you cannot say "that's no excuse for a rookie Caleb, Getsy has another year of experience!"
That is logically ridiculous.
