A few days ago people were posting that Tweet about our recent attrition and it made me think of LWS and all the data he had accumulated on attrition from the past. So I dug up an old post of his where he had all SEC attrition for about 14 years. I looked at the most recent 5 years from the date of the post - which was mid-season 2016, and made a league average. This is then compared to our own attrition over the same relative classes.
The outcome is nothing too wild, but we still have almost 10% more attrition than average and our 5th year guys are sorely missing. I figure we'll be short on RS SRs again in a couple years, considering the 2017 class is already cut nearly in half. Including NFL/graduation, we only have 3 RS SRs left out of a class of 30. Now, quite a few programs aren't able to hold onto guys for 5 years. Still, the average in the SEC is having 5 in-house RS SRs (not including incoming transfers). We are down a couple and 1 is a longsnapper.
This is non-graduating/NFL attrition, as LWS states: "Failures were counted for: Non-qualifiers, players getting dismissed, failing school, transfers, just quit playing football or unknown reasons. If players left school early for NFL, I do not count them as failing to complete eligibility."
We could also look at the overall number that have left to include graduating and the NFL, though this additional margin shouldn't be too different from other schools, especially considering how few have left early. I don't think our use of JUCOs or transfers has been unusual either, though the 3 grad transfers last year have accelerated things a bit for that class. The 4 JUCOs, plus 2 medical retirements, from 2016 also brings that class up to 48% already gone. Tifwiw.
