The post players Rose has recruited have not really improved. Davies is the last guy that had a good post game, but he came in with a pretty good game already.
Davis already had a post game when he got to BYU.
BYU consistently has an issue with big athletic players who have not developed even one solid go-to move. If you look at the WCC, each team seems to have 2-3 big slow white dudes who can catch the ball in the post and score......BYU has one and the previous dude that played that role played 3 years ago.
