Detroit Lions quarterback Matthew Stafford and rehabbing Colts quarterback Andrew Luck, plus stories from the NFL training camp trail.

Stafford, a Texan, on his love of his adopted city, Detroit; on why he's enthused about new coach Matt Patricia, on a memorable and painful game he won as a rookie, on baseball memories growing up on the same team with Clayton Kershaw, and on the pain of never having won a playoff game, and on how bizarre it is that he's now in his 10th season.

Luck, on the state of his surgically repaired shoulder 19 months after labrum surgery, on his daily mindset after months of frustration over the slow progress of his rehab, on the dark place he lived in when he wondered if he'd ever play football again, on how "The Way of Zen" helped him get his mind right, and on the democratic process of new coach Frank Reich.
