As a UK fan, I would like for the ultra "one and dones" (Anthony Davis, DeMarcus Cousins, John Wall, Karl Anthony Towns, and others to stay longer, but this would be for "my benefit" not theirs. Secondly, if "one and dones" stay longer, it means the future "one and dones" UK would have signed will go someplace else because they will seek more playing time.
Finally, UK's tremendous recruiting success under Coach Cal is based in large part on him being a "player's first coach". Cal has successfully marketed this recruiting approach to the point where it has become his brand. The reality is UK's incredible team success over the last 8 years is based on significant player turnover each year. Such an approach creates some fan frustration and elevated levels of expectations (often unrealistic).
Notwithstanding some fan grumbling about "one and dones", UK has not enjoyed the level of team success it has experienced during any prior 8 year period since Adolph Rupp coached UK in the late 40's and early 50's. Prior to Coach Cal becoming our coach, UK had not been to a Final Four in 12 years. Since Cal arrived, UK has been to the Final Four 4 times in 8 years and has won a national championship.
Since Cal arrived, UK has enjoyed its greatest national media exposure and it has been able to sign the largest number of high quality players in its storied basketball history. Indeed, in UK's remarkable basketball history, these times, under Coach Cal are special. We should appreciate this precious present rather than whine when one of our players opts to make millions in the NBA.
