Indianapolis Colts head coach Frank Reich, entering his second season in charge of the team this year, spoke on Tuesday about lessons he learned from Hall of Fame coach Tony Dungy. Dungy, 63, coached Indianapolis for seven seasons in the 2000s, leading the Peyton Manning–quarterbacked franchise to a Super Bowl win in 2006-07.

Reich, 57, served as a coaching intern two years prior to his first season as the Colts' offensive assistant in 2008. After that season, however, Dungy would leave the franchise, retiring from the NFL and becoming a television broadcaster.

Here's what Reich had to say about what he's learned from the coaching great and two-time Super Bowl champion in Dungy via The Athletic's Zak Keefer on Twitter:

Don't take this the wrong way, but my concern level never kicks in. That's one thing I think I've always felt, but I learned anything — and I learned a lot from Tony Dungy working with him — he literally never flinched. Even when our best players got hurt, you'd look at him and he was never overly concerned. And so I just think that's important. You can do both. You can have a genuine care and love for your players, wanna do everything you can do to help them get better, but you also understand in this business that if a guy's not ready, it has to be next man up. And if you really don't believe that deep down in, I just think that shows. For those reasons, I don't get concerned.

Reich references the doubt surrounding former first-overall pick and seventh-year QB Andrew Luck, who's nursing a calf injury.

In order to maintain a calm presence in training camp, Reich has yet to show panic in a moment that proves uncertain regarding the long-term health for four-time Pro-Bowler Luck.
