Kemba Walker and the Boston Celtics take on James Harden, Russell Westbrook and the Houston Rockets on Saturday.

Walker could return to the lineup after missing games this week due to his knee injury, although nothing has been confirmed yet.

The Celtics' floor general spoke to Rachel Nichols of ESPN about the challenge of facing Westbrook and Harden:

“Those guys are just incredible basketball players,” Walker said. “They know how to play the game. They know how to play off each other. You know, James is one of the best scorers we've seen in a very long time. And of course Russ, he's non-stop, he gives 100 percent each and every night.”

The Rockets are 38-20 on the season behind the stellar play of Harden and Westbrook. Both MVPs are on their way to making the All-NBA teams.

Walker played in 46 games for the Celtics before the All-Star break. He averaged 21.8 points, 4.1 rebounds and 5.0 assists while shooting 42.9 percent from the field, 38.8 percent from beyond the arc and 86.6 percent from the free-throw line.

Walker signed with the Celtics because he was eager to go on a deep run in the playoffs. This is one of the best players in the NBA who hasn’t been able to showcase his game on the brightest stage since the Charlotte Hornets were rarely good with him.

For the Celtics to win the East, Walker, Jayson TatumJaylen Brown and Gordon Hayward have to play at a high level, and not separately. All four guys have to be dominant together for the C’s to ultimately win the conference and title.
