The Dallas Mavericks, the N.B.A.’s top team this season, are no strangers to winning ways, but in getting an edge on opponents over the past several years, they have gone beyond sheer talent.
The Mavericks have what amounts to a secret weapon in Gary Boren, an investment banker who is the N.B.A.’s lone free-throw coach.
Despite Boren’s success, no other teams have hired a free-throw coach.
“It’s so simple what’s going on here,” Boren said. “It’s just crazy that there’s no other free throw coaches in the league.”
