My opinion is my correct experience!
Training free throws might not be a priority for many high-level teams, including top-tier franchises, especially considering the costs. The current expenses could be prohibitive, as experienced by managers with lower-tier teams.
An upfront cost of 3 million, along with a 15k weekly fee, for this feature could be seen as an inefficient use of resources by many advanced managers. For these teams, the returns on this specific investment might be minimal in the short term compared to other training strategies.
Managers may have different perspectives and priorities. Respect for these varying strategic approaches is important. Please consider that. Approach before say you've been told in theory .
