I don't understand the obsession with a 5th guard, as if the Coach is wedded to playing only a certain way: 3 guards and 2 bigs or sometimes 4 and a big. He adapts playing style according to his roster.
While the current collection of tall girls does not have one who can play a mobile wing, I understand that Ayanna would qualify. And, if he wants to play 3 guards, Caroline is the best candidate among them to play wing but it does not preclude playing Azzi, Paige and Nika at the same time. But, as someone pointed out, how easily some people forget about Aubrey.
Were it not for the injury, the effort to remold Aubrey would have progressed this year. That Aubrey project will continue - he likes her athleticism, they are trying to fix the weaknesses - although it lost a good year for it to progress. For coaches, this is the fun of challenges in College BB: coaching players to find their best positions and roles, refining their abilities and expanding their capabilities.
Yes, I understand the fans' trauma from this year's injuries mostly to guards and Geno's proclivity of play incoming guards as wings or occasionally F (see Katie Lou and Gabby.....didn't Megan play as a guard as well in HS?) feeds the more-guards-needed notion but he really looks at the roster and tries to balance the use of his players' qualities in maximizing their chances to win.
The roster for next year is fine - different from heavy use of the tall guards at his disposal this year, since he likes to play fast. The forwards will be a bit crowded for playing time since Dorka is coming back (which is quite good....). There six tall ones, with Aubrey - if you count her there - a seventh. So, if the coaching staff continues with the remaking of Aubrey into guard/wing and expanding Ayanna's role to wing as well (knowing this coaching staff, I am certain they are looking at that), the ability to play fast remains undiminished. But, the possibilities grow for playing against bigger teams with advantage in mobility and flexibility while the ability to dominate smaller teams remains intact.
