Durr is more a combo guard IIRC, but she certainly CAN play the 1 (and the 2). I think she's more similar to Taurasi than to Jefferson. I could see her and Nurse starting, much like when UCONN started Doty and Hayes - Neither is a PURE PG, but UCONN has not had very many of those over the years (Rizzotti, Williams, Swanier, Dixon and now Jefferson come to mind). And Jen was so long ago she might have been a combo guard too.
I would say players like Conlon, Taurasi, Hayes, Montgomery, and even Bird were combo guards, mainly because they were very capable scorers as well as leaders running the team. Not that Jefferson isn't a capable scorer, or Rizzotti for that matter but just trying to draw a bit of an analogy for differences...
