Player-coach used to be a thing in professional sports a long, long time ago. There's a reason you don't have it anymore. A coach can't be expected to take the long-term view while also expecting to contribute. Most examples were players near the end of their career and they didn't tend to do very well.
The only place you see it is in fun adult leagues. Perhaps the message then is that Coinbase wants to be less professional and more amateur-like?
