I don't think many players are brought to Uconn to be high volume low efficiency scorers. With many other good scoring options, Geno can try to wean all players from 2pt shots in the low 40's percentage range. It is possible Westbrook has the ability to get that kind of a shot frequently, but that doesn't mean it will be encouraged.
She had a little better than average efficiency and significantly better volume if I remember right her last year at Tennessee. That is compared to average players. By Uconn starter standards her volume would probably be pretty good, but efficiency worse than they are used to. She might be the best go to option with the shot clock running out, but would have to increase efficiency in a major way to earn enough shots on a great team to be one of the nation's leading scorers. Uconn teams look for 50% two point shots and only settle for less than than that when they have too.
Evina will be a beneficiary of more good looks because of players like Anna, Paige and Nika, and I would like to see her in the game with one or two of those players, but that benefit will more relate to her 3pt shots than her ability to create one on one.
