Seems like both parties (UCONN and Mir) should have figured this ( lack of fit or adequate skills) during the recruiting process.
This one on paper seemed like a dubious fit. Mir has skills that so mirror Aubrey, but she is two inches shorter. Both may have figured there was some guard play in her future if she rounded out her game, but what Geno recruited was a 5-11 PF.
Having said that I am pretty sure she can contribute quite well at a school that is willing to accept her minuses in exchange for her strength's. Unlike some other transfers, she was productive in her limited minutes last year. With the returnees and additions, however, she still was at best third on the depth chart at PF behind Aaliyah and Aubrey, probably fourth behind using Dorka there as well, and possibly fifth if Geno used a wing at that position as he did often last year.
I think your quote also could apply to the situation with Caroline and Saylor. Very similar players, Caroline ranked a little higher, probably only room for one not two. In that case I think Saylor may have committed first, but once Caroline signed on a similar situation existed there.
