Things could get crazy this week.

The 49ers experienced a ?Win Monday? ? the term given to a players? day off following a victory. The 49ers earned a two-day break (Tuesdays are traditional days off for players during the season) with a 33-30 overtime win at the Seattle Seahawks.

Running back Frank Gore came by the 49ers? practice facility on Monday for some treatment. He was walking gingerly after being the focus of the Seahawks? defense one day earlier.

But Gore figures to get re-energized Wednesday when he catches the first glimpse of offensive coordinator Mike Martz?s game plan against the Detroit Lions.

You see, Lions coach Rod Marinelli fired Martz as offensive coordinator after last season. Marinelli was not fond of Martz?s approach. The Lions attempted 641 passes (including 54 quarterback sacks), while running the ball only 324 times last season.

?We want to win every game, but I know this is a game he?ll want to go in and do a lot of crazy stuff,? Gore said. ?It?ll be fun.?

Gore was among the happiest players on the 49ers to see quarterback J.T. O?Sullivan pass for 321 yards on Sunday. The performance snapped a streak of 60 consecutive games that the 49ers failed to produce a 300-yard passer.

Gore has enjoyed some success against the Seahawks in the past.

He gained 507 yards in his past four games against Seattle.

?Yeah, I knew they weren?t going to let me go crazy,? Gore said.

?I know defensive coordinators are going to try to stop me and I?m just happy the receivers and quarterback did a great job. Now teams see that we can throw the ball and make plays down the field, so I can go crazy again.?

The one concern with the passing game is the number of hits O?Sullivan has absorbed through two games. He has already been sacked 12 times, including eight on Sunday.

?I saw him today,? Gore said. ?He looked pretty good. The hits probably weren?t that hard.?

The Moose & Goose Show

Former Cowboys fullback Darryl (Moose) Johnston counted the 49ers among his biggest rivals during his playing days. Old rivalries die hard ? or maybe it?s just a fullback thing.

During Patrick Willis? 86-yard interception touchdown return, Johnston was openly rooting for Seahawks fullback Leonard Weaver to prevent the touchdown. That?s OK, unless you?re supposed to be an impartial television analyst. Johnston was calling the action in the Fox TV booth.

?Come on, Leonard!? Johnston shouted on the air during Willis? runback. ?Get him, Leonard!? Despite the encouragement he was receiving from Johnston, Weaver failed at his diving attempt to tackle Willis near the 10-yard line.

Then, Johnston, speaking to broadcast partner Tony Siragusa, said: ?I had a bad feeling on that one, Goose, when Patrick Willis got it and there was some open space. He is so athletic.?

Defending the defense

Coach Mike Nolan and defensive coordinator Greg Manusky went against conventional wisdom with their game plan. The Seahawks had just three healthy receivers after starter Logan Payne was injured early in the game.

Yet, the 49ers employed a defensive scheme that removed outside linebacker Manny Lawson from the action and replaced him with another safety ? a fifth defensive back.

The 49ers? pass defense was effective. Seattle quarterback Matt Hasselbeck completed just 50 percent of his passes and had a career-low 42.5 passer rating. But the Seahawks gauged the 49ers on the ground with 169 rushing yards.

?I did feel that going into the game, from a matchup standpoint, it gave us the best chance to win player on player,? Nolan said.

?I thought it was very effective in what we tried to accomplish.?

Jennings misses time

Right tackle Jonas Jennings sustained an unspecified right shoulder injury that kept him out of action in the second half.

Jennings has missed all or parts of 33 games (out of 50) since signing with the 49ers as a free agent in 2005. Jennings got off to a slow start in Sunday?s game with two false starts and a holding penalty. But Nolan said Jennings will regain his starting job from veteran Barry Sims when he?s healthy again. The 49ers had no updates on injuries to Jennings, safety Dashon Goldson (knee) or cornerback Shawntae Spencer (knee).

Getting one back

The 49ers made up for their opening-week home loss with the road victory against the Seahawks, the four-time defending NFC West champions. ?We lost a home game last week against Arizona,? Nolan said. ?You?d like to think if you?re going to make a run at something, you take care of your home. So we had to steal one on the road, so to speak. Now, Seattle?s dealing with the same thing.?
