Greg Roman wants the San Francisco 49ers' offense to be more fluid in Week 4.

The 49ers gave Frank Gore just one carry in the entire second half.

“With what [the Cardinals] were doing going into the game, I mean, they were selling out, like, full, waving-the-flag selling out to stop the run,” Roman said Thursday. “You always want to get Frank involved, but again, you’ve got to kind of weigh how much, when and how. And then you’ve got to factor in everything that you think is going to happen and then everything that is actually happening.” 

The 49ers had a 14-6 lead at halftime.

“So, you got to be fluid with it,” Roman continued. “I think, for example last week, we had a plan that was different than the one we utilized early in the game and the other plan was working pretty good. So, shoot, we’re not getting to that other plan. And that’s pretty much every week, to be honest with you.”
