Whether you realize it or not, college basketball has always been about the one and done.
How could any sport that crowns champions based on a single-elimination, 64-team tournament be otherwise described?
March Madness is built on late runs and momentum, often fueled by the play of one individual rather than an entire team.
While UNC has always been something of a college basketball powerhouse, it was the heroics of Sean May in 2005 that propelled the Tar Heels to their first title since 1993.
While May -- like so many others who have danced in March -- was able to reach the pinnacle of college basketball, his game did not translate to the NBA.
Here are some other March Madness legends who killed it in college but couldn't be found after making the leap to the next level.
Harold Miner: From 'Baby Jordan' to only four NBA seasons.
Throwing down dunks with the number 23 on his back, Harold Miner was once dubbed “Baby Jordan.”
Although he was taken 12th overall in the 1992 NBA Draft by the Miami Heat and won two Slam Dunk Contests, Baby Jordan played just four seasons in the league.

Adam Morrison: Scoring leader to four-year career.
In 2006, Adam Morrison was the NCAA Division I scoring leader, a first-team All-American and Co-Player of the Year.
Even though Morrison “won” two NBA championships with the Lakers (2009-2010), his career lasted just four years.
Chris Duhon: From rookie of the year to assistant coach at a small college.
In 2001, Chris Duhon was named ACC Rookie of the Year and won a national championship with Duke.
Brief stints with the Bulls, Knicks, Magic and Lakers followed for Duhon. He's currently an assistant coach at Marshall.

In addition to being crowned the tournament's Most Outstanding Player in 1992, Hurley was also a first-team All-American the following season.
Hurley was taken seventh overall in the 1993 NBA Draft, but a car accident, in which he went through the windshield and almost died, ruined any chance Hurley had at making it big.

In 2007, in his one season at Ohio State, Greg Oden led the Buckeyes to a national championship appearance against Florida. They lost 84-75.

Acie Law: Texas A&M hero to professional player in Greece.
A first-team All-American and Bob Cousy Award winner in 2007, Former Texas A&M Aggie Acie Law always had flair for the dramatic.

God Shammgod: From Providence student-athlete to just a student.
In 1997, with one of the greatest names in NCAA history, Shammgod led the Providence Friars to the Elite Eight.
Shammgod's legacy grows every time someone crosses the crap out of a defender; he also went back to Providence to get his degree and is currently helping his former program grow.
Bo Kimble: Cinderella story to short professional career.
Despite the loss of teammate and friend Hank Gathers just months earlier, Bo Kimble led 11th-seeded Loyola Marymount on a Cinderella run to the 1990 Elite Eight.
Kimble was taken by the Clippers with the eighth overall pick in the 1990 NBA Draft, only to have his career end just three years later.
