A forgotten factor regarding who brings the ball up and who is the PG in the half court set relates to fatigue and minutes played. Paige has probably played major minutes on every team she has played for in contested games. So if she is a do everything type of player for you and someone else can safely advance it to the half-court, why not give her a few seconds to catch her breath on a regular basis.
Azzi could probably be a good point guard, and although usually your point guard brings it up, it doesn't have to be the same person that runs the offense the most from the half-court set, and when your point guard is playing 35+ minutes per game it is a way of extending her effectiveness a few minutes.
Last year we played at a little faster pace than most teams, but not by a lot. I wonder if some of that was to "save Paige" and Christyn too for that matter since they both played big minutes. Nika in particular would be more effective running all the time. With more depth and shooters, I hope we press and fast break more even if it means reducing the minutes of our very best players. It will reduce the effective minutes of other teams stars as well, and I believe our second unit would beat most teams second unit by more than our starters would beat their starters.
