If we don't see Azzi back for a few minutes Saturday I wouldn't expect her back. Having said that I fully expect her back Saturday. Why all the prep if she/they know she can't play again this season? As to her impact, there should be no question that it will be a positive one.
Azzi has been shooting hundreds of shots a day over many years so I would doubt she hasn't done so (as soon as she was able) during this down time. So she won't need to find her shot again and we all know she can get a shot up in a split second with almost no space. She will remain an excellent ball handler as well. So, IMO, being in game shape will be the only real mountain to climb.
Her return and resultant impact on the chemistry/flow will be very different than last season with Paige's late season return. In that scenario the team was playing very fluidly with Nika as the point guard so the team had to adjust with Paige's reinsertion. Nika and Paige play the point very differntly so that was a considerable adjustment for everyone. That won't happen with Azzi's return. Nika will remain at point and the rotation will return/expand to what it was at the start of the season. Everyone's roles basically remain the same but their minutes will be reduced some. And lastly, unlike last season when the offense was in a good rhythm at the tim of Paige's return - it is unquestionably not at this time, so Azzi's reintroduction will be more of a reset than a change (and certainly not a disruption).
I don't think Azzi's late return will be anything but a positive. Some instant offense, a great outside threat, another great ball handler with great vision and ability to find her own shot, a very good defender a great foul shooter - what's not to like. Looking forward to her return as I'm sure she, the coaching staff and her teammates are as well. Let's finish at full strength and see where we end up!
