“If you have success and it’s premature and it builds this air about you, that’s not right: You get your butt kicked,” Rivera said this summer. “If for whatever reason we come out and say, ‘Well, we arrived, man; we got this,’ then we’re not going to get better. We’re not going to go back and learn from the basics. We’re not going to understand what it takes to get back to where we need to be.”
