Undeterred by his struggles in the preseason, Robert Griffin III remains confident he possesses what it takes to become a productive pocket passer and “put up some big numbers and do some great things,” he said before Monday’s practice at Redskins Park.

Griffin has become the subject of scrutiny amid preseason struggles by the first-team offense, which played poorly in Saturday’s 23-17 loss to the Baltimore Ravens. In failing to lead his teammates into the end zone, Griffin, who continued to appear shaky in the pocket, completed 5 of 8 passes for 30 yards with an interception. He was sacked three times and had a 27.1 passer rating.

In 10 possessions spanning three preseason games, Griffin failed to engineer a touchdown drive. With Washington’s starters scheduled to sit out Thursday’s preseason finale against the Tampa Bay Buccaneers, Griffin won’t play again until the Sept. 7 season opener against Houston Texans.

Many in the organization have called for patience as Coach Jay Gruden attempts to help Griffin become primarily a pocket passer for the first time in his career. But from the overwhelmingly angry tone of things on social media, fans appear concerned Griffin may never get it. Griffin has no such doubts.

“We just take it and move forward,” said Griffin, who finished the preseason with a 46 passer rating. “We can’t worry about what outsiders think and what they say. We’ve got to keep moving forward here. We know what we’ve got to do to be successful, and that’s what we’re gonna do.”

At this stage of the season, Griffin is not overly concerned about his ineffectiveness and subpar statistics. The first-team offense had only one bad performance, Griffin believes.

“As an offense, we put together a bad game,” he said. The other starters on offense “go as I go, so I have to play better. But I thought we did a good job in the first two preseason games.”

Griffin, however, acknowledged he must improve.

“There’s a lot of things that we felt like we could have done better. A lot of things I felt like I could have done better,” he said. “You’re never going to put together a perfect game, but we would like to come out and have a better showing than we did this last game.

“We had two good preseason games. This last one was bad. That’s the last thing people remember. For us, we know that it is still the preseason. We’re still working through some kinks and working to get in rhythm. We’ll continue to that and be ready for Houston.”
