I wonder a bit about how this clash of roles is going. Jana may picture herself as a multi-talented forward. A big with a good handle that can drive to the basket, incorporating various spin moves, and shoot from the three occasionally. On her teams she was far more the number 1 option than even Paige is on this on.
Geno has apparently defined her as a low post C period. In terms of what this team needs most, he is probably correct, but whether Jana is allowed to expand her game, not really expand, but just do what she has done previously against much less competition, is in question I think.
I presume Geno has largely taken 3's off the table for her. Maybe foul line jumpers if not guarded too, although I would hope she could in time hit enough of those to make it a weapon. The area I think Geno should cut her some slack on, is drives to the basket, where for her size she is remarkably good, but it might come with more turnovers than Geno can stand.
Her previous teams needed her to be a volume scorer, and to show all her scoring versatility. At Uconn her efforts need to reach a high level of efficiency with minimal turnovers, or they will be discouraged. The learning curve in the post will continue, but if she can be good enough at high post jump shots if unguarded, and mix in a few drives to the hoop, her offensive upside is so much higher.
