It's a by-product of everything he preaches. Be your best, regardless of circumstances. Focus on one play at a time. He can't then start tearing into people on the sideline for a bad play on game day. He encourages and they move on to the next one. Then in the film room you can tear into people for their mistakes because at that point it's a learning situation.
That said, he's the coach on the sideline of a losing team. He's going to get hate no matter what happens, and with a fan base that's busy still blaming play calling, of all things, for every loss, it's not a stretch that they're also irritated with the clapping and the positivity.
