There are several things that are factor but I don't view it has hate toward UT. There are just factors about how kids chose where they go to school.
First off, as of today Kimbrow and Redmond don't have commitable offers to Tennessee. IMO, we would NOT take their commitments next week either. So if they are ready to commit, they will end up committing elsewhere.
Memphis is closer to 7 other SEC schools than to Tennessee. Being closer is a HUGE factor with families so they can go see their kids play. Outside of relationships with coaches recruiting them, distance to family and friends is the next factor when considering schools.
Memphis recruiting has always been sparadic throughout Tennessee history. More so since the 70s and more so since Fulmer took a more national approach.
The conference was so weak in the 90s and CPF was able to get elite players from the Carolinas, Virginia, Georgia, Florida, Louisiana, Mississippi and Alabama that Memphis and the state foe that matter, were not a priority. The record in the 90s would dictate the strategy was pretty good.
