In the era of "one and done", it's no surprise that many of the members of last year's MaxPreps High School All-American teams are playing a significant role, as freshmen, in this year's NCAA Tournament.
Here's a look at where each of the 25 All-Americans went to school and the contributions they are making for their college team.
First Team
Harrison Barnes, Ames (Iowa) - North Carolina
While Barnes' selection as a preseason All-American hasn't quite panned out, the Iowa sensation is still the leading scorer for the No. 2 seed in the East bracket with 15.0 points per game.
Kyrie Irving, St. Patrick (Elizabeth, N.J.) - Duke
Irving got off to a strong start for the Blue Devils, averaging 17.4 points per game, but he injured his ankle in the eighth game of the year and missed the rest of the regular season. However one of the big developments in the first round of the tournament is the possibility that Irving will return after nearly a three-month layoff.
