Devils advocate:
Some of the best coaches in American sports have been dudes that weren’t really that good when they played or never played in the league they coached in.

Not disagreeing with you. Just pointing out that it’s not simply white and black. Data is data and it’s up to you to decide what has value and what doesn’t. Writing off data because it doesn’t fit some archetype you have predetermined is objectively sub-optimal 🤷‍♂️
