I think what we are seeing from BBanks this year is a bigger learning curve for her when it comes to a truly organized and structured approach to basketball. UCONN still allows for a fair degree of freedom on offense, but only after you have first understood the rudiments of the flow that Geno wants the team to execute. Sort of like the difference between 1-on-1 and 'improvization on a Theme'.
This also fits into what Phil said earlier in the thread, where he talks about Brianna not yet being fully comfortable with the difference between "always do THIS in this situation" and "we prefer to do THAT, but you have other options". BBanks has such ridiculous physical skills that it's easy to see how this could be the case for her coming in. She probably did not have to absorb nearly as much organization as she needs to do at UCONN; she could just create on her own. She has a truly amazing handle to go along with blazing speed---we haven't seen 1% of what she can do. I am hoping for a big jump next year, but it might be longer.
