I don't mean to step on SCspur's toes by trying to think of some rationale, but here goes (I will preface by stating that I will have TN 2nd next week).
The LVs had some really bad losses after they lost Keyen and before they lost Horston -- Auburn, Alabama, Florida (moreso the margin of defeat), & the Paige-less Huskies (once again margin); therefore, getting Jordan back might not be the entire answer. Rickea certainly carried the Bulldogs to many victories, especially the latter part of her freshman year, but she often gets in black-hole mode after her initial footwork. Sometimes she is cold and sometimes the on-ball defense is excellent, which leads to a lot of shots with a low %. Curiously, on D her reactionary footwork isn't as good (and has issues with help D -- ask your old friend Annie), but she somewhat makes up for it with her long arms resulting in steals, deflections, & highlight reel blocks. They have added so many quality pieces, but sometimes it takes time for those to gel. I think that they will work out the kinks in non-conference play and be strong in SEC games. I just don't see anyone other than SC coming close to matching their talent and individual experience.
