The AP reports: LeBron James dunked the first time he touched the ball and scored 34 points—22 in the first half—as the Cavaliers, who waited nine days between playoff games after a first-round sweep, shook off some early rust and pulled away for a 99-72 win over the Hawks in their Eastern Conference semifinal opener on Tuesday. Showing why he was voted the league’s best player in a landslide, James added 10 rebounds, three assists and four steals as the top-seeded Cavs won their fifth straight lopsided game in a postseason that has so far mirrored the best regular season in franchise history… Maurice Williams added 21 points for Cleveland, which became the first team since the 2004 Detroit Pistons to win each of its five playoff games by double figures. With the Cavs up by 21, James was pulled with 4:29 left—extra down time before Game 2 on Thursday night at Quicken Loans Arena, where the Cavaliers are 42-2. Josh Smith scored 22 and Mike Bibby 19 for the Hawks, who needed seven games to get past Miami and are playing in the second round for the first time in 10 years. They weren’t happy with their start in this series, going 9-for-30 and scoring just 28 points after halftime.
