I don’t know which players start next season. But who starts matters. For example, if the starting lineup doesn’t have enough good perimeter shooters then your team is going to fail against better opponents. Same for rebounders, defenders, etc.
Unlike baseball, however, there are no designated players. So, having shooters, shot-blockers, etc. on the bench is not really a valuable enough thing. Bench players provide the most value in being able to come in and keep the team clicking, pickup someone playing poorly, keep players fresh, etc. But just like in the starting lineup, the more well-rounded the players off the bench are the more productive they probably are.
Worrying about pacifying players with sufficient “minutes” to equate with starting is a recipe for failure. It’s form over function, and to me it equates a basketball team to a video game or something – and I don’t think successful basketball teams work that way in reality.
