Numbers preview: Eastern Conference finals – Boston Celtics vs. Cleveland Cavaliers
The Cleveland Cavaliers are 32-4 in the Eastern Conference playoffs since LeBron James returned home in 2014. So it’s fair if you already have the champs penciled in for a third straight matchup with the Golden State Warriors in The Finals.
After a lackluster second half of the regular season and a first round with a few close calls, the Cavs took care of business in their conference semifinals sweep of the Toronto Raptors. Their defense was significantly better and their offense remained unstoppable.
The last East team to beat LeBron James in the playoffs is the same team standing in the way of him making his seventh straight trip to The Finals. But this is an entirely different Boston Celtics team than the one that was a two possessions from winning a championship in 2010. Celtics president of basketball operations Danny Ainge and coach Brad Stevens have quickly rebuilt a contender while retaining the assets they got for tearing one down.
The Celtics have home-court advantage, but will have to recover quickly from a seven-game series with the Washington Wizards for Game 1 on Wednesday (8:30 p.m. ET, TNT). The Cavs may have to shake off some rust, but an extended rest seemed to do them good in the last round.
