Martial arts are an individual pursuit. Software development is a team sport, which is precisely where your analogy falls apart. The best boxing coaches are not the best boxers. The best football, basketball coaches, sure, they may have experience as players, but you don't see the best players consistently go on to become great coaches. That's because leadership and coaching is a different skillset. I agree with a lot of e folks in this thread that perhaps the best combination here is a good (servant) leader to lead the team as a group, and an individual like a tech lead to train up on technical skill.
