WASHINGTON – The first two games in D.J. Augustin’s absence, Charlotte Bobcats coach Paul Silas let rookie point guard Kemba Walker find his way.

Now, after two losses by a combined 50 points, Silas takes back the offense. Expect a heavy dose of called plays when the Bobcats take on the Philadelphia 76ers Friday night.

“I don’t want him taking 19 (shots), and only making four,’’ Silas said of Walker following a 92-75 loss to the Washington Wizards. “We’ll start executing the offense, not just (leaning on) the high pick-and-roll, not jacking up shots. He’ll learn.’’

Silas wasn’t angry with Walker, thrust into the point-guard role with Augustin resting an inflamed big right toe. Rather, Silas is upset with himself for not giving Walker more structure. The Bobcats shot well under 40 percent in losses to the New York Knicks Tuesday and these Wizards Wednesday.

The Bobcats played Wednesday without their two top scorers: Augustin, out at least a week, and shooting guard Gerald Henderson, a pre-game scratch due to a back contusion suffered when Knick Jared Jeffries clobbered him Tuesday on a drive to the rim.

Henderson hopes to play in Philadelphia, his hometown.

“I couldn’t move. I wasn’t mobile enough’’ to play, Henderson said.

With Henderson out, Matt Carroll started and impressed, with 17 points on 7-of-10 shooting. But there was just too little to stay with even the 3-15 Wizards, with Augustin, Henderson, Corey Maggette and Reggie Williams all unavailable.

“Talent is the most important thing; if you don’t have it, you won’t win and it’s very hard to execute,’’ Silas said. “When our two leading scorers don’t play, how do we score?’’

Carroll concurred, saying the injuries have thrust players suddenly into roles for which they’re not prepared.

“First, guys are playing out of position,’’ Carroll said. “Second, guys are playing a lot more minutes than they’re used to, You go from 10 to 35 minutes, it has an effect.’’

Offense wasn’t the only problem. Though forward Tyrus Thomas had his best game of the season with 13 points, nine blocks and nine rebounds, the Wizards constantly got to the rim. By game’s end, 60 of Washington’s 92 points were scored in the lane.

Several Bobcats said after the Knicks game they were embarrassed. If so, that wasn’t apparent by the start of this game.

“If that’s how they felt,’’ Silas said, “next time they have to do something about it.’’
