RICHMOND, Va. -- On Sunday, the Redskins released their first unofficial depth chart for Thursday's preseason opener against the Cleveland Browns.

The depth chart by no means is set, as roster moves and injuries are frequent this time of year. With a 10-man rookie draft class producing and competing for spots on both sides of the ball, head coach Jay Gruden mentioned that the upcoming first week of preseason is no different than the previous weeks in Richmond.

"The first preseason game – not that we're taking it lightly -- but it's more about we're still in training camp mode," Gruden said during a press conference Sunday morning.

"First preseason game is mainly you're going to call your first two or three install-type plays that you have in, let the players play, play fast, and not so much worry about scheme as you normally would. Still, we want to get them prepared for what they will possibly see so they can adapt and play fast and we can hopefully have some positive plays against Cleveland."

With a quarterback battle at the headline of camp, reps are the primary source of evaluation so far for Gruden, who said "I think they've all done some really good things without a doubt and they've all done some things that we've got to coach. That's just the way it is at the quarterback position."

"Colt's [McCoy] got the most experience in the system, but he still hasn't played a whole lot. He hasn't taken a lot of reps. Last year it was all about Alex [Smith], the year before that it was all about Kirk [Cousins], and getting them ready," Gruden added. "Case [Keenum] has all the reps, but he doesn't have much experience in the system. He's doing a nice job, and obviously Dwayne [Haskins] is a rookie. All three of them have shown flashes of being really good and really productive, and all three have shown flashes of, 'Hey, we've got to get better."
