I wasn't on the board when Holdsclaw played (not sure the BY was in existence) but I dont think she (or Catchings) was really hated or despised by anyone? She was a like Tennessee's Maya Moore in that she was pretty mild mannered player who just showed up and would dominate without any antics. Like Maya, I think most were in awe of her as a player without a lot of negative commentary. Semeka Randall is definitely the better choice from that era since she was heavily recruited by Geno but chose Tennessee, had a scuffle with Hansmeyer, threw the ball of Svet's head and her nickname of "Boo" Randall came from getting booed relentlessly by UCONN fans. She also hit a game winner vs UCONN and the rivalry was more even during her time (4-3 in Tennessee's favor, both teams won a title).
Arike is also right up there too. I'd say the top few are:
1. Diggins
2. Parker
3. Ogunbowale
4. Randall
For 5th, maybe Marina Mabrey or Cappie Pondexter. Mabrey talked trash and Cappie got into a tiff with Geno after a game which created some drama.
