NAPA — The Raiders ended training camp Thursday looking not much different from when they started.

The roster is essentially the same, and so is the depth chart. The Raiders, who face Detroit on Saturday at O.co Coliseum, are 0-2 in exhibitions, just as they were at the same point a year ago.

Running back Darren McFadden was the best and most explosive player on the roster when the Raiders reported to camp, just as he is as they head for Alameda.

Injuries to wide receivers Denarius Moore (hamstring) and Jacoby Ford (foot) were troublesome, although both could be ready for the season opener Sept. 10 against San Diego.

Rookie coach Dennis Allen, taking a few minutes to wrap up with the media amid the background noise of moving vans being packed to transport the operation back to Alameda, didn’t claim to solve all the ills of a franchise that hasn’t had a winning season since 2002.

But he thinks it was a good start.

“I thought we had a chance to get better,” Allen said. “Our guys worked extremely hard. We still have a long way to go and a lot of things we need to improve on, but I thought it was a good foundation to build on.”

The Raiders installed an offense with West Coast elements, along with a zone running scheme with bootlegs and rollouts, and a multiple attacking defense with blitzing from different angles, along with zone and man-to-man coverages.

Players were evaluated for special teams, which will be sorted out through the cutdowns to 75 players by Monday and finally to 53 by Aug. 31. It was all accomplished in a structured environment Allen hopes will result in discipline and efficiency.

“It’s organized — just knowing where you need to be every moment, every day, with everything lined out for you,” safety Michael Huff said. “You know what everybody expects of you. If you stray, you can’t argue, because it’s been outlined for you since Day 1.”

Defensive tackle Richard Seymour likes what he sees.

“We bonded well. I think there’s a better understanding of where we’re headed in terms of the season,” said Seymour, whose participation of late has been as an observer as the Raiders monitor his sore knees. “I thought it was a great sequential progression from the OTAs into training camp.”

With the new collective bargaining agreement eliminating two-a-day practices (only a brief walk-through is allowed as a second workout in a day), Allen made sure to pack as much as he could into the allotted time.

“It was long. Grueling, but fair,” defensive tackle Tommy Kelly said. “It’s been tough — probably the hardest camp I ever did, but I’m in good shape, so I don’t have no complaints.”

Although there could be some maneuvering as the rosters are cut down, it appears that with the 2012 Raiders, what you see is what you’re going to get.

“There’s been competition, but the guys who are listed No. 1 on the depth chart right now, we feel those are the guys that give us the best chance of winning,” Allen said.

The Lions-Raiders game, which starts at 4 p.m., will not be televised live locally. It will be aired at 7 p.m. on KICU-36 and at 8 p.m. on the NFL Network.

Seymour will be a game-day decision against Detroit, as will tight ends Richard Gordon (ribs) and Tory Humphrey (hamstring).
