I'm assuming you mean "Jennings"... yes, like a previous poster has already mentioned, there's no SEC rule against transferring within the conference. The reason it seldom happens is because coaches typically put conditions on releases to prevent transfers from transferring to another conference school... In this case, Mitchell gave all of his players no conditions (blanket transfers) allowing them to transfer to any school in the nation regardless of conference affiliation.
Jennings also considered LSU and UGA, both are also SEC schools.
