Turns out this was absolutely worth the wait. Epic performances usually are. After nine days off, the Mavericks finally got a game Tuesday night — and a memorable performance by Dirk Nowitzki. Nowitzki and Kevin Durant — two pure-bred stars — squared off magnificently in Game 1 of the Western Conference finals. Durant was great. But nobody was topping Nowitzki or the Mavericks on this night. He had one of the most outrageous games in Mavericks’ playoff history, the primary reason the Mavericks took charge late in the first half and got pit bull tough in the second to score a 121-112 victory over Durant and the Oklahoma City Thunder in the best-of-7 opener. Nowitzki was a monster with 48 points. He had six rebounds, four assists and four blocks for good measure. “I was really looking for my shot early,” he said. “For a shooter, when the first couple shots go in, it’s great for the confidence, and I just kept attacking.” And attacking. And attacking.
