INDIANAPOLIS -- Jim Caldwell's NFL résumé has success written all over it, from the very top all the way down to very end.

He was assistant coach and quarterback coach with the Indianapolis from 2002-08, winning a Super Bowl with them in 2006. Caldwell took over for Tony Dungy and led the Indianapolis Colts to a 14-0 start and another Super Bowl appearance in his first season in 2009.

Caldwell was fired after a 2-14 season -- and the end of Peyton Manning’s career in Indianapolis -- but rebounded nicely by being the Baltimore Ravens' offensive coordinator when they won the Super Bowl in 2012.

But Caldwell admits he wasn’t sure he would end up being a head coach in the NFL again.

Those thoughts ended when the Detroit Lions (7-9 last season) named him their head coach last month.

So Manning, Joe Flacco, and now Calvin “Megatron” Johnson.

That’s not a bad group of players to coach for Caldwell.

“Fact of the matter is, very rare do you get a second opportunity,” Caldwell said. “Not only a second, but this is actually the third (time) for me if you include my stint in college as well. I was hoping, but I was also very, very satisfied working extremely hard at what I was doing in terms of coaching the position or being an offensive coordinator, whatever helped a team win. I’m not able to forecast the future. But I certainly indeed hoped that I did get another opportunity. I’m glad it happened.”

Caldwell, who was rather reserved as head coach of the Colts, noted how he’s grown as a coach from what he learned with the Colts and during his two seasons with the Ravens.

“One of things about our business is the fact that if you don’t feel like you’ve grown or developed each and every day, you’re in the wrong business," he said. "I learned something different each and every day. I had a great 10 years (in Indianapolis). We obviously had a lot of success and certainly learned a lot about what to do in terms of offensive football, learning how to develop was important in terms of how we went about doing things, but also winning consistently has a certain sound to it.”
