This game will serve as an example of what can happen to a team that plays too conservatively, concentrating more on lack of mistakes than on finding ways to score.
Denver had about the worst game imaginable, and is not more than a fair team to start with. Their coach and their personnel decisions are suspect. Still, they damn near won.
Now, it is early and it is preseason and keeping it simple is understandable. Still, the team also has to learn to step on the throat of struggling opponents and pour it on. If opponents are allowed to stay close, all it takes is one missed assignment or turnover and they can win it.
Hopefully, the 9ers will rev it up as the preseason progresses.
