San Francisco 49ers' offensive coordinator Greg Roman is expected to be a head coaching candidate in the offseason.

Roman is credited with maximizing the collective talent of the 49ers' offense with a balance attack.

"When the play call comes in, I know exactly what he's thinking, what we're trying to do, and what we're trying to accomplish," Alex Smith said. "I think the whole offense is constantly putting us in good situations, him especially. Really, thinking through things all week and putting us in good situations. I don't think there's any play that comes that we don't feel has the potential to be a great play."

Roman called the 49ers' record-setting win over the Bills in which they rushed and passed for over 300 yards.

"I think it's just a credit to the players and I think it's a credit to what we can accomplish as we move forward," Roman said. "I'm not a big statistical guy -- don't get caught up in it. But, at the same time, just in the normal course of events being able to put up that kind of production, obviously, we're doing something right."
