They're needed for depth and with potential to outplay their rank, but a Championship contender wouldn't have but a few sprinkled in their class. Georgia has signed some nice classes over the past 6 years and has 23 3* guys from '18-'23 out of 151 commits (15%) which is about all you should have on a % basis if you want to contend for 'chips, but of course they also have 30+ 5* guys over that period so I guess that helps!
