Totally agree. Someone who just understands that you need to go talk to customers and actually try to sell whatever you're building ASAP is going to fare way better as a founder than someone who learned what PMF is during their MBA but doesn't want to get out and do the dirty work.

What do you mean by "better"? There's room for lots of people to have jobs off the field. Think about all of the support staff we never see on TV during the game. Or off the field even during the game. The announcer/sports commentator, the coach, the physical therapists and doctors, the people that work the grounds. Stephen Curry doesn't work in vacuum and neither does Jeff Dean.
