Even if you have no attrition you should have a 4-person class every 4th year. I don't think those are the problem. Maybe the problem is that our 4-man classes have not really had much attrition so it made it harder to recruit elite players immediately afterwards. The 2017 class was a departure from 2007 and 2014 and we're seeing what seems to be some consistency from 2018-2021 in that we don't have one class with 4 top 100 multi-year starters in it and hopefully our attrition will be more natural. We'll see. I have no complaints with where we're at.
