ALAMEDA -- From the beginning of the Dennis Allen era, the Raiders promised to be multiple on defense, mixing zone with man-to-man and changing up occasionally between 4-3 and 3-4 alignments and using the blitz as a weapon.

Offense, and the running game in particular, was a different story. The Raiders were going back to the zone scheme full time, a system they ran with coach Tom Cable from 2007 through 2009.

During the bye week, with a stalled running game and a 1-4 record, Allen and offensive coordinator Greg Knapp came to the same conclusion Hue Jackson did when he was handed the keys to the offense by Al Davis as offensive coordinator in 2010:

The running game would be better suited with more diversity in terms of blocking.

It was one of the first things Tampa Bay coach Greg Schiano noticed when comparing the pre-bye and post-bye Raiders on film.

"They added a little bit in the run game, they started running some more gap scheme stuff," Schiano told Bay Area reporters by conference call.

Given that Knapp has a longstanding belief in the zone scheme, chances are the change was made reluctantly, although out of necessity.

Knapp worked with Alex Gibbs, the guru of the zone system, in Atlanta. Purists of the zone blocking system, and that includes Cable, don't believe in deviation. Rather than fire off at a specific defender, zone runs call for more lateral movement and clearing of an area. It takes time to perfect and execute.

Running backs hesitate only long enough to take one cut and head upfield when they find a lane.

During training camp, line coach Frank Pollack, brought in by Knapp to install the scheme, said "If you just dabble in it, you won't be able to take it to the next level without having mass chaos."

Fast-forward to the fourth quarter of the Raiders' 26-16 win over Kansas City on Sunday. The Raiders rushed for 95 yards on 20 carries with a mixture of zone and more straight-ahead gap runs.

"We definitely increased our gap run blocking scheme to get a better balance and keep defenses honest, and we've done it well, so we'll keep that same kind of formula working," Knapp said. "It's a good changeup."

Center Stefen Wisniewski can see where immersing the offense in the zone scheme before blending it with gap blocking was of some benefit.

"It makes a lot of sense. That's where our coaches came from and that's their mindset," Wisniewski said. "Coming in it was zone, zone, zone, zone. But I think they're starting to get to know us better and we're getting to know them and so they're seeing we can be successful doing both."

Knapp said outside zone plays accounted for much of the fourth-quarter yardage, and his hope against Tampa Bay is to get the steady gains going earlier.

"I would like to have a little more consistency on the 3- to 6-yard gains throughout the half," Knapp said. "But I was glad the guys stayed patient up front. I kept reminding them, 'Hey, we're going to stay with this. The score says it's OK. We're going to stay patient with our game.' "

  • The Raiders announced the Tampa Bay game would be televised locally, the 12th consecutive game that has been shown in the local market.

    It was the second time the Raiders asked for an extension of the Thursday deadline. A win over Jacksonville was televised with an attendance of 51,634 with the help of a new rule which allows a "sellout" to be declared if 85 percent of the non-suite tickets are sold.

  • Middle linebacker Rolando McClain will be a game-time decision with a toe injury incurred Wednesday. If McClain can't play, Travis Goethel, listed as probable with a back injury, would play middle linebacker in the base defense.

  • Tampa Bay, already without two-time Pro Bowl right guard Davin Joseph for the season, lost left guard Carl Nicks to a toe injury that needs surgery. Nicks is the Bucs' top offensive lineman.

  • Although McClain is potentially out and linebacker and special teams player Keenan Clayton is doubtful with a shoulder injury, Allen would not commit to putting Aaron Curry on the 53-man roster.

    The Raiders have until Wednesday to either promote Curry from the physically unable to perform list, place him on injured reserve or release him.

  • Defensive tackle Richard Seymour was fined $15,750 for what the NFL called "an unnecessary late hit" on Chiefs quarterback Matt Cassel. Seymour was called for a personal foul on the play, one of just two Raiders penalties in the game.
