As Geno recognizes and has mentioned many times, it's a new day in WBB. Don't understand his reluctance to welcome transfers.
IMHO it's not a reluctance to welcome transfers, as much as it's an evaluation to see how they will fit, whether one grad year, or multiple undergrad years. If a transfer comes in after more than one year at a school, there's a learning curve as to how UConn approaches everything - practices, games, travel, etc. Evina, Dorka, and Lou all fit in seamlessly and adopted whatever role was asked of them, and we were incredibly lucky to watch them in a UConn jersey.
When coaches look at the list of transfers, questions of why are they leaving, how did they perform at their school, what are they looking for at a new school, are there any issues/baggage that they are carrying, all come up. If a player is unrealistic at their original school, that probably won't change at a new one. That's not to say that an unhappy player at a school would not fit in at UConn, however over the past few years, by our view on the outside, the teams have been very close. One ripple to that, and poof.
Geno doesn't make promises to any player, whether a recruit or a transfer. There are plenty of players who want/need a promise, and that's not his style. It seems that he and the staff are very cautious on adding players this way, and I don't think he'd ever have multiple transfers in, as other schools have done for this season. During the height of the transfer portal window in the spring, this is what Geno was looking at (by class), and that looked pretty darn good.
Jana's injury happened after the portal, and Ayanna, Caroline & Azzi's issues occurred after the season started, so there'd be no way fix it with a transfer.
