Troy, like their SEC neighbors, likes to oversign classes dramatically -- and then simply not renew scholarships of those who may not be as good as the new recruits coming in. It's a pretty despicable practice, even though all scholarships are only guaranteed for one year; kids take it on faith when they sign that they'll be there 4 years if they stay clean and try hard.
Not the case.
Their last five classes had: 25, 32, 33, 40(!) and 34.
That's more than 60 players OVER what OU has recruited the past five years. How much better do you think OU or any school could be if they routinely over signed and then simply didn't renew scholarships of kids they decided they didn't want, anymore.
It helped Alabama come back from almost getting the death penalty in football to winning a national title in just a few years. They are one of the worst offenders of over signing in the SEC, along with LSU. Most of the SEC does it, though, while most other conferences simply don't allow it (yes the NCAA has not addressed this issue...so long as schools make it to 85 by the time fall practice starts).
Just wanted you all to have some perspective on how Troy can be so much better than OU when they are both from non BCS conferences.
