Cool. He seems like a well-meaning and hard-working guy which is what you want in a franchise cornerstone. Whether it's language skills or improved defense, that sort of humility and accountability is a great sign. It's why I love Jaylen Brown, whatever he says or tweets about the guy is clearly working hard to get better and fix the things we Cs fans are complaining about online. Contrast to Pablo Sandoval, for example, although it seems like more and more elite athletes have this sort of high professionalism built into them these days.
