Sunday Preview

The Milwaukee Bucks ended a long playoff drought in the first round, as they notched their first postseason series win since 2001. They had the best regular-season record in the NBA and then swept the Detroit Pistons to advance to the second round.

Milwaukee's competition will be tougher in this round, as it takes on the Boston Celtics, who swept the Indiana Pacers in the first round.

The Bucks and Celtics were the only teams to sweep their first-round opponents.

Last year, Milwaukee and Boston met in the first round of the Eastern Conference playoffs. The Celtics won that series in seven games.

"This is a different team than last year, but at the same time, it never hurts to have a little bit of a chip on your shoulder from last year based off how that series went," Bucks guard Pat Connaughton said, according to Field Level Media (h/t ESPN.com).

Milwaukee and Boston have met six times in the postseason, with the Celtics winning five of those series.

In Sunday's second game, the two-time defending NBA champion Golden State Warriors will look to get off to a good start against the Houston Rockets, who are led by last year's MVP, James Harden.

The Warriors, who are the No. 1 seed in the Western Conference, had a surprising first-round series against the Los Angeles Clippers, as it took them six games to advance. Golden State lost two home games during that series.

Last year, the Warriors and Rockets met in the Western Conference Finals, with Golden State winning in seven games.

Although Houston has been eliminated by Golden State in three of the past four postseasons—with the Warriors winning three NBA championships in that span—it's not backing away from the challenge.

"That's what I want; I want to face them," Rockets center Clint Capela said, according to Field Level Media (h/t ESPN.com). "If you want to be a champion, you've got to beat the champion."

One concern for the Warriors is that star guards Stephen Curry and Klay Thompson are both questionable with ankle injuries for Game 1. Both injuries were suffered during Golden State's Game 6 win over Los Angeles on Friday.

According to Nick Friedell of ESPN, Warriors coach Steve Kerr wanted to see how Curry's and Thompson's ankles responded to the medical treatment they received Saturday morning before making a decision on whether either will play.
