Redskins coach Jay Gruden still supportive of Robert Griffin III

ASHBURN, Va. -- Redskins coach Jay Gruden remains supportive of quarterback Robert Griffin III, reiterating there is no competition for the starting job -- even if Griffin hasn't fully outplayed the backups this preseason.

Griffin, who suffered a concussion against Detroit on Thursday, participated fully for a second consecutive practice Tuesday. Gruden said Griffin will see a neurologist Thursday and, if cleared, will play at Baltimore on Saturday.

The Redskins announced in January that Griffin would be the starter, and nothing has altered their opinion through nearly one month of practice and two preseason games. But Griffin and the first-team offense are coming off a tough outing vs. Detroit; he was sacked three times on eight pass dropbacks, though he did little to help himself in the pocket by moving into pressure on a few plays. Eventually the hits took a toll and Griffin left with a concussion.

For Gruden, he's looking at a bigger body of work than just what Griffin -- and backups Colt McCoy and Kirk Cousins -- has done in two preseason games. Griffin completed 6 of 13 passes for 44 yards and a 54.6 passer rating in those games. Cousins and McCoy, who are alternating in the No. 2 role, have passer ratings of 118.3 and 131.6, respectively, in their outings vs. backups.

"We're judging not just the performance on three drives in the preseason game, but the performance through OTAs and training camp," Gruden said. "That's why we're going the way we're going."

The Redskins' starting offense, with Griffin at quarterback, has not scored a touchdown this summer -- nor did it produce one in the 2014 preseason. Griffin did have one pass dropped two weeks ago vs. Cleveland that would have resulted in a touchdown.

It did not help that the first-team offense produced 4 rushing yards on four first-down runs against Detroit, leaving them in bad down-and-distance situations.

Griffin has not talked to the media since his injury.

"First of all, it's not about him. It's about that unit, the first-team unit," Gruden said. "We've got to have better protection out of all of them. As soon as we start to make it about one guy, that's not what we're trying to do. We'd like to get something going with the first unit, period. With Robert in general, just get the ball out of his hands, move the ball and make good, sound decisions. Let the players around him help him."

Gruden also blamed the play-calling for some of Griffin's struggles.

"We just have to make sure we do our best to put Robert in a good place with the play calls and try to get something going offensively," Gruden said. "Every play is its own entity. You'd like to say, 'He could've done this, could've done that.' From a play-calling standpoint and from a quarterback standpoint, we've got to stay out of the negative plays."
