Here is Dunn's poem, "Losing Steps." It was most likely influenced by his experience as an athlete as it contains basketball imagery.
It's probably a Sunday morning
in a pickup game, and it's clear
you've begun to leave
fewer people behind.
Your fakes are as good as ever,
but when you move
you're like the Southern Pacific
the first time a car kept up with it,
your opponent at your hip,
with you all the way
to the rim. Five years earlier
he'd have been part of the air
that stayed behind you
in your ascendance.
On the sidelines they're saying,
He's lost a step
In a few more years
it's adult night in a gymnasium
streaked with the abrupt scuff marks
of high schoolers, and another step
leaves you like a wire
burned out in a radio.
You're playing defense,
someone jukes right, goes left,
and you're not fooled
but he's past you anyway,
dust in your eyes,
a few more points against you.
Suddenly you're fifty;
if you know anything about steps
you're playing chess
with an old, complicated friend.
But you're walking to a schoolyard
where kids are playing full-court,
the value of the experience, a worn down
basketball under your arm,
your legs hanging from your waist
like misplaced sloths in a country
known for its cheetahs and its sunsets
