Great question and discussion @Jill Schieve. IMHO you can't be an effective or objective coach if you're in the boat. You don't have to coach from the drum seat or steering platform though. You can coach from a chase boat, from (a long) dock, or riding your bicycle alongside (if your practice site is, say, a canal with a bike path alongside)... all of which I've seen done effectively. And it's what you have to do if you don't fit the makeup of the team (eg. are a male coach for a women's crew). If you want to step into coaching, I'd recommend doing it with a separate crew that you have not been an integral part of. Maybe that's a beginner crew, or a rec crew, or a completely different division crew. Coaching a boat you've been paddling in yourself is fraught with drama, politics, resentment, and "who the hell are you to tell me how to paddle?" kinds of sentiments. Plus, you can be accused of giving yourself the best seat , never sparing yourself, etc. And as plenty of folks have pointed out, you cannot see what's going on - how people paddle in different seats, how they mesh with those around them (or not), etc. Imagine doing a video review session... you're telling Judy to drop and rotate more, but you're maybe doing the exact same thing and you never call yourself out on it or work on your own form. Indefensible and awkward as heck. As a coach you have to make hard decisions... you have to hold people accountable, decide who spares when, decide seating arrangements, etc. It's a bit like being a parent... you can't parent AND be your kid's best friend. There are boundaries you need to establish and not cross. You can't be a teammate (and gripe about a practice, or commiserate on a challenge) and a coach at the same time. So paddle with one team, coach another. That is the cleanest, most sustainable way to do it.
