Really how many kids are going to give that interview ('I was un-coachable and really still am some' but 'so grateful they (her coaches) didn't give up on me')? Geno has said that Nika is unique and he certainly is right on that one. Geno has many times described Nika as a pain in the ass and at the same time he credits her with changing, in a positive sense, the way the team has played each of her three seasons, and how he wouldn't want her to change the core of who she is.
In his preseason exchange with her when he told her 'if she stayed the way she was he would sit her ass on the bench even if he had no other guards' but if she listened to him and did what he and the team needed her to do she would have a great season'. He got that right as well. She listened, responded and has been this season the best version of herself on the court.
Nika's dad Darko at one point early on in Nika's time at Uconn, said in response to Geno's and Nika's embattled relationship in essence, 'she needs that and good luck to Geno'. I'm sure they still have their moments, but I would guess the temperature is way down, and the duration short and adjustments are immediately forthcoming. We won't see a tearful Nika on the bench unable to look Geno in eye as he pokes her arm to force her to listen, or her sitting out a key match up, anymore. IMO, they are way beyond that and truly rely on and trust one another.
Nika has said the reason that she, after years of wanting it, had Loyalty tattooed on the side of her neck was because that is the most important thing to her. She has self admittedly grown up and transformed herself leading into this season, I would speculate driven by, at least in equal parts or more likely greater so by, what she felt her team needed from her than a personal desire. I think much of the identity of the team that Geno has credited as being reflective of Nika is her sense of the great significance of loyalty. They truly care for and play their hearts out for each other.
