Cavaliers turn nightmares into a dream come true. Reported by Marla Ride-in-hour. In the visitors locker room, their fourth consecutive trip to the N.B.A. Finals secure, the Cavaliers weren’t dousing each other with water. They were singing rap artist Meek Mill’s anthem Dreams and Nightmares. They now had their share of both. But until mid-April it was the nightmares that kept recurring, pushing the dreams aside, making it harder and harder to remember they were playing for the love of the game and for each other. The Cavs were proud of themselves for surviving the turmoil. Proud for tuning out the doubters. Proud for playing defense in the biggest game of the season when no one thought they could.
