Mike Singletary struggled when he was head coach of the San Francisco 49ers.

But Singletary believes his second stint as a head coach would be better.

"I wouldn't be here if I didn't think there would be a next time," said Singletary, Vikings special assistant to the head coach/linebackers. "How long will it take? I don't know. When the Lord is ready, I'll be ready."

The 49ers had an 18-22 record under Singletary before he was fired.

"I didn't have a lot of experience, but they gave me the job. And the experience I got will help me on this journey. The next time around, I'll make sure I have everything in order. I'll be better prepared for the challenge."
