"We'll consistently see what we want to be a little bit more than occasionally," Smith said.
"I wanted (Martz)," he said. "I knew what he would bring to the table. (But) given our personnel, we need to get back where we belong."
•He isn't too concerned about Matt Forte's contract stalemate.
Smith pointed out Forte has not missed any team functions.
"I look at offseason as time to negotiate," Smith said. "You do it different ways. He doesn't feel good about his contract situation. He voiced that. It's no more than that. I don't make too big a deal out of it."
Smith believes the Bears are better at running back.
He said Michael Bush will bring more to the Bears than Marion Barber did because Bush can help the team more outside the tackles and in the passing game.
"Michael is a complete running back," Smith said.
Adding Bush wasn't necessarily because the team did not want to promote Kahlil Bell to be the No. 2 back.
"But wouldn't we be even stronger with Kahlil here and Michael Bush?" Smith said. "It's about strength in numbers as much as anything."
Smith did acknowledge Bell's fumbling is a concern.
"We've seen what he can do with the ball when it's secured, now he has to secure it more often," Smith said.
