Rose could have changed but chose not to do so.

Players intuitively know when leadership is competent or incompetent.

Rose was competent for many years until he refused to apply the new knowledge in the game that coincidently emerged almost precisely at the time BYU joined the WCC and ran into the likes of the up to date Randy Bennett.

Some people see change for the better coming and get up to speed, others not so much.

Same is true among CBers. Some very knowledgeable basketball posters here were VERY slow to pick up on the compelling importance of modern analytics. For example, it seemed to take forever for some to apprehend the centrality of "points per possession" (PPP), obvious as that should have been.

Doesn't matter how much you know technically or fundamentally about the game. If you don't understand and inculcate the important numbers in your game, you can't win at a high level anymore, as a player or a coach.

After the eye opening embarrassment in MLB which ignored outsider Bill James' work for two decades until Billy Bean in 2002, the NBA immediately jumped on the work of basketball thinkers from outside the profession who developed meaningful math for cagers.

Among NCAA coaches, all saw the analytics freight train coming, some jumped on board while others, such as Rose, clung to their old ways and weakened their performance.
