OU suffers from a 40% attrition rate, which means they are getting about 60% of the class on the field for meaningful reps. For a big time school I'm not sure this is better, worse or about average. I would need to see the numbers. You do realize that there are years where some attrition is a good thing don't you? Sometimes it's better to trim the fat early rather than have a player hang around 4 or 5 years without any meaningful contributions. Many have enough sense to see the writing on the wall that they are too far down the depth chart to ever play a meaningful down for OU, and they go elsewhere where they can start. I see it happen all the time Now if the players leaving are all highly sought after recruits, that's another story. But like I said, I would want to know how that averages out against all of the other major power 5 schools attrition rates before i call it a problem.
