For us it would boil down to Aubrey, Fritz, MEM / time. Sara might be the best of the bunch, but not a real need.
The big girl fits our needs if she can play inside.
Just my opinion.
Sara's dad says she wants to "win"; nobody is better situated to "win" than ISU over the next couple years.
Sara's dad says she wants to play with teammates who work as hard as she does. She can meet Emily Ryan at the practice facility at 6am.
As for need, this is no time to be sentimental. MEM is a nice player (my personal favorite) and can be instant offense off the bench; I think she'd embrace that role. Diew can fill in from 2-5, so she'll get time. We don't know exactly what we have with Fritz, but it would never hurt to play deeper into the bench anyway - there's nothing wrong with going eight or nine deep. I personally believe Aubrey is considering the transfer portal with the situation as it is now.
Sara S. is a near perfect fit for us. She shoots the three at a top 20% rate, is a proven scorer in a P5 conference and can play the point - we can't count on Emily staying healthy with the minutes she logs, and it'd be great to have a contingency plan.
Again, this is the perfect time to go mercenary for a change. Add the available 6'6 athletic player with incredible potential and go guns blazing after the proven shooting guard. For ISU, we have an unprecedented opportunity that would make us a serious contender for (at least) the next two years - it's no time to hesitate!
Postscript: I have no idea if Kennedy B or Sara S have interest in ISU, or would be happy playing with three established "stars", but I hope we're at least exploring the possibility!
