Last Sunday was one of the best Kaepernick has played in the big picture," Roman said on Thursday. "From A to Z, he was magnificent on all levels and that was great to see."
Kaepernick hasn't been viewed as explosive when running as much as he could be. There are several scrambles where he took a passive approach before sliding or running out of bounds to either sideline.
Roman said the team is not over-cautious on their approach, but they don't want him to carry the ball every play. He said when the game begins, anything can happen.
"[We don't have a] limit for Kaepernick as we don't want him carrying the ball every play," Roman said. "I definitely think there's a certain number in our mind that takes place. Once we get to the game it's time to go and be ready."
The biggest reason to be optimistic going forward is the health of the 49ers wide receivers. With Michael Crabtree back and Mario Manningham progressing after both guys came off serious injuries, Roman expects the chemistry to gel instantly.
For the beginning of the year, the offensive coordinator felt the execution wasn't there with Anquan Boldin and Vernon Davis being the only targets on offense. For this Sunday, the 49ers don't have an excuse if the offense plays poorly with Davis, Crabtree and Boldin all on the field.
"Any time you can bring your best players back on the field, it's going to have a huge impact on things," Roman said. "Earlier in the season, we didn't have that kind of chemistry. We're starting to see it develop now. In the end, it comes down to execution on the field and [this will be] exciting to see."
