The 49er defense has forced 5 or more turnovers in 3 games this season -- the only team in the league to do so.
Sunday they forced 6 turnovers against the Lions, but their offense could only manage 3 points off those turnovers.
That is the most disturbing part of the victory and Monday head coach Mike Singletary agreed that you have to find a way to capitalize on your opponents mistakes.
"This is not acceptable. It's never acceptable, and I don't think it's acceptable to our offense or anyone on our offense. I think we made the plays that we needed to make. I think there were a couple of times that we did execute very well," said Singletary.
