It has been a long an winding road for UCONN recruiting in the class of 2019. There are a couple of additional notes besides the ones that you have already covered.
The strength of the class early on was at the wing position and I'm including Brunelle at that position. UCONN appears to be in good shape with Brunelle and Haley Jones. UCONN has room for both because of the added versatility of Jones to play the 2 and Brunelle to play the 4. Haley Jones has separated herself from the pack of 2019 wings. Despite not making the USA U16 team last summer she has been absolutely killing it since them and leading the #1 HS team in the country. When the recruiting services get around to updating their 2019 class ranking I expect Haley not to be lower than consensus Top 3.
I have always been of the opinion that UCONN was looking at bringing in a PG (maybe combo) in the 2019 to have some overlap with Crystal. In that regard UCONN has evaluated at least 3 such players( Chang, Peoples, & Cooke) and has declined on all three. There are still 3 PG/Combo guards being evaluated by UCONN (Horston, Correa, & Osborne). With the departure of AEH, the 2019 class is the first opportunity to find a replacement and might explain the renewed interest in these three players. My guess is that 1 of these 3 ends up at UCONN. Any of the three would work, Correa appears to have the inside track because of proximity to UCONN. Osborne is a longer shot because she's from California. Horston is the longest shot of all because she has already sat through too many recruiting pitches where schools are telling her she is "THE WOMAN". Horston coming to UCONN to play a lesser role than "THE WOMAN" would be a very hard sales job for the UCONN staff. NEVER underestimate Geno and this staff meaning if they decide that Horston is the best fit, they will convince her to come to UCONN. Recall that when Charli Collier decided not come, UCONN did not have a lot of time to react and was not in good shape with ONO.
Boston to UCONN also makes some sense even if Ezi still decides to come to UCONN. Boston's strong physical build is the biggest attraction to UCONN. ONO and EZI are agile PF types that may struggle with the physicality in the post- with Boston you gain physicality and not at the expense of mobility. Boston's home is 45 minutes from UCONN campus-significant because when Boston was selected for USA basketball team her family and community started a go fund me page so that her family could go to Argentina to support her. 4 years of supporting Boston at UCONN will be significantly less burdensome on the family and community than any of the other major college program (Louisville, South Carolina, Maryland) that are heavily recruiting her. Others reasons Boston to UCONN makes sense is that Camara may not be on the roster, Kyla Irwin will be a senior and Ezi becomes WNBA draft eligible after the 2021. Boston is also expanding her game to beyond the arc and that would enable her to find minutes away from the post as well.
Having Boston , Amihere & Brunelle does not make a lot of sense for UCONN if Ezi decides to come to UCONN, for many of the reasons that have already been stated: Camara may still be on the roster, Brunelle has the versatility to play the 4, Kyla Irwin will still be on the roster. Amihere would also be somewhat duplicative of both ONO and Ezi.
For 2019 my wish list has evolved and the operative word is versatility.
Boston (5/4)
Brunelle (3/4)
Jones (2/3)
Correa(1/2)
