I think your comment about the last 20 minutes against Arizona is telling. It also raises a strategic question. Others have said that Liv can dominate inside against weak competition and I agree, but like others I think she can't do the same against top competition, and it is more than a bad game or two, there is an established relationship there.
So suppose Liv is doing fine against the Big East but now you are in the elite 8 or farther and playing a team with physical bigs that are good defenders. Do you bench a year long starter because you don't like her match-up in that game? Do you game-plan away from her offense and tell the team not to feed her down low, in essence give up on her offense but have her just concentrate on defense and rebounding? Do you start her but sub early and significantly reduce her minutes?
I think as a team we spend the season creating a well oiled machine to produce a high number of easy shots with largely the same strategy. I think it is frustrating to Geno that largely because of Liv, the year long strategy doesn't work against the great teams. It may be telling that in discussing Gorka he said Aaliyah might get the most touches down low next year, because she finishes well around the basket.
I think there is a middle ground here. Geno often tries to get his players to concentrate on what they do well, and eliminate the things they don't. That depends on the opposition. Instead of saying lets keep giving Liv the ball down low against a player like Boston or Brink expecting her to suddenly start making a high percentage of them, throw in the towel on that strategy. Don't give her the ball there against top defenders and tell her to kick it back out if she does get it.
But if Aaliyah or Gorka can score against top defenders down low, you can still pursue that, but tell Liv this game you job is rebounding and defense, and to her defense she has been ok against top competition there. But feeding her the ball as much as Paige against good bigs is trying to fit a square peg in a round hole, and probably a bad coaching decision as well, because that is asking someone to do something they cannot do well against that level of competition.
