I don't buy it, I think he has the upperclassmen is always the best bet mentality. But if you're right he is a braver man than me, he might be coaching for his job next season if he doesn't make the CFP with this schedule this year. Getting to the CFP probable gives you 2/3 more years to recruit and an extension after the season.
Another thing, nowadays a QB ball out 2 years and they're a gone (after the 3rd yr), maybe you will get a guy that comes back for his 3rd year as a starter to win a title, but most of the time they're 3 and done
