Georgia and Alabama provide the highest level of remuneration. Oklahoma, Texas A&M and FSU are also supposedly providing large payments, but they do not have Foundations in place. Arkansas' Foundation has the second most amount of capital next to Alabama's. The Razorbacks' Foundation raised $150M in funding to modernize their stadium a couple of years ago. The Hunts, Tysons and Waltons endowed the Razorback foundation.
A PSU donor told me that they "selectively pay", but since the Sandusky scandal still reverberates nationally, they are more discriminant about payments because PSU is still considered a strong academic institution and they do not wish to mar its reputation any further.
The SEC pays players but some schools boast sophisticated operations and others have not "caught on". The 'National Press' caught Mississippi "red handed", but Emmert was able to minimize the punishment.
Except for Oregon, the Pac 10 and the ACC are minimally active in the "bag game" at present. I do not think that USC will ever seriously play the "bag game" anymore.
