UT can give out 30 scholarships to the Seniors who compose the '10 class, but if they do then 5 must be backcounted to the '09 class. That way you do not violate the 25 rule. This class if UT does sign 30 will have atleast Half of that class enrolling in UT in January. Now all of this is mute if UT goes above the 85 limit and if signing 30 does then they cannot sign 30. It's a paper game...
NCAA
1. No More than 25 scholarships per year
2. No More than 85 scholarships per team
3. If the previous year you did not sign 25 and your not at the 85 limit then you can backcount to the previous class up to that class' 25 or the 85 limit whichever comes first.
SEC
1. No more than 28 signees per year (this is for those recruits you don't expect to gain admission) (Nutt Rule) Still only 25 can be part of the '10 class
