Listen to Dwyane Wade talk these days and it sounds like catharsis, like a man exhaling. He has survived his personal and professional tumult and come out smiling. Life is good, and Tuesday brought just one more reason to think so. He’d had minor surgery on his troublesome left knee the day before. “Started my rehab today,” Wade told us. “I’m up and walking. Got rid of the crutches today.” Obstacles shed. Moving forward.
