Duke’s Jeff Capel learned from his father’s toughness

Jeff Capel knew, he wrote.

He knew ALS was an incurable disease after participating in the Ice Bucket Challenge a couple of years ago.

But his father’s diagnosis left Capel in tears, the Duke associate head coach penned in a letter on The Players’ Tribune that posted Wednesday.

A father who taught toughness. A son who's learning what it means.

The Capel family learned in spring of 2016 that the coach’s father, also Jeff, has ALS, a progressive neurological disease.
