The Atlanta Hawks suffered a double blow on Wednesday when they were beaten 97-89 by the Cleveland Cavaliers in Game One of the Eastern Conference finals and lost DeMarre Carroll to what looked like a serious knee injury.
J.R. Smith caught fire off the bench with 28 points, including eight three-pointers, and LeBron James tallied 31 points, eight rebounds and six assists as the Cavaliers grabbed the lead in the best-of-seven series.
“I was just trying to take good shots. I got into a rhythm early and stayed aggressive,” Smith told reporters.
Smith, who has seen his reputation tainted by sour exits at previous teams, has thrived since being acquired by the Cavaliers in a mid-season trade.
“I’m just trying to be myself,” he said. “They seem to accept that more here.”
Adding injury to the insult of dropping Game One on their home floor, the Hawks lost leading playoff scorer Carroll in the fourth quarter when he planted his foot and fell on a non-contact play.
Carroll was carried off and was due to undergo an MRI to reveal the extent of the damage yesterday.
“At this point I think the doctors are saying it’s a knee sprain, we’ll know more …,” said Atlanta coach Mike Budenholzer. “He’s a big player who has impacted on both ends of the floor; other people will have opportunities.”
Jeff Teague had a team-high 27 points for the Hawks, while Al Horford added 16.
Atlanta battled to a 51-51 tie at halftime but lost control in the third quarter where the Cavs took a seven-point edge at the end of the period.
Smith drained a trio of early three-pointers in the fourth to provide an 85-67 advantage that held up down the stretch.
The top-seeded Hawks, who have excelled due to tight teamwork all season, were pounded by Cleveland inside and outrebounded 49-37. The Cavaliers got double-doubles from Timofey Mozgov (10 points, 11 rebounds) and Tristan Thompson (14 points, 10 rebounds).
Game Two is today in Atlanta.
