Washington Redskins quarterback Alex Smith said there’s no additional burden on his shoulders after the team lost three offensive starters to injured reserve in guards Brandon Scherff and Shawn Lauvao and wide receiver Paul Richardson. The 14th-year veteran said everyone has to pick up the slack.

“If anything, there’s more of an emphasis of just doing your job,” Smith said. “I think that’s what this is about. I’ve got to be accountable. I’ve got to hold up my end. There’s certainly no making up for anything. I think you can get in trouble trying to do that.

"I’ve got to do my job a little better. If everybody kind of takes that mentality, we’ll be all right.”

The Redskins offense had already been up and down throughout the season, playing well when the run game is clicking but struggling in second halves and when playing from behind. The passing offense ranks 24th in the league and the offense’s 20 points per game rank 25th.

Despite being without Richardson and slot receiver Jamison Crowder (ankle) and probably starting an offensive lineman who was just signed this week, Smith doesn’t expect significant changes when the team travels to play the Tampa Bay Buccaneers on Sunday.

“I don’t know about change,” Smith said. “As an offense collectively, I don’t think you look to all of a sudden become something different. … We all have to step up.

“The thousands and thousands of reps that we’ve had, you’re trying to condense into a few days to get ready. So, I think, communication is the key. There’s going to be a lot of times it’s nonverbal communication there. On the road, loud, everybody’s got to be on the same page, locked in even though you can’t hear. That makes it even tougher. Going against a good D-line, even more of an emphasis on it.”
