It make no sense that a player practice one only skill per week, but in BB it happens.
These are BB league guys though... not NBA legends...
You've never seen a highschooler? or college kid, focus on only one skill at a practice for a week? an emphasis? I have.
Are these usually the best players on the team/in the world, no. But they exist. and it happens. I wouldn't say it "makes no sense" but I would say it's "not Ideal". Maybe in BB some of the players are guys that otherwise would only have the special olympcis to look forward to do to Inclusion rules and discrimination? who can say for the backstory of how the BB leagues were formed? Maybe these players, also have full-time jobs, plus familes, and dont have the time commitment to work on more than 1 skill per week. Think of their families and children!
