Well on the subject of PGs, going back to 2009 every WNBA Champ except one had Bird, Whalen, Gray, Sloot, Taurasi (I know, sometimes more a 2G than PG) or Cloud, and this year will be either Gray or Sloot again. Very few of those players were selected as MOP for the playoffs, but it appears you have to have a premier guard to win a Title.
Anyway Hiedeman isn't a PG at all, she's a small 2G. Career average of 2.4 apg. Hasn't cracked double digit scoring average yet in her career. They'd really be well advised to upgrade at that position.
