Education Secretary Arne Duncan entered some of the most contentious debates in college sports on Thursday when, in a speech at the N.C.A.A. convention, he called for stricter consequences for college teams that do not graduate their athletes and said the N.B.A.'s age-minimum policy sets up young athletes for failure.
"Why do we allow the N.C.A.A, why do we allow universities, why do we allow sports to be tainted when the vast majority of coaches and athletic directors are striving to instill the right values?" said Duncan, who was a co-captain of his Harvard basketball team and played in an Australian professional league from 1987 until 1991.
He said his time as a college athlete was one of the most valuable periods of his life, but feared the N.B.A.'s age rule, which requires that a player be at least 19 years old and at least one year removed from high school before entering the league, does a disservice to athletes.
