REGENSBURG (David Hein's Eye on the Future) - "Incompletion" means something is missing. And that was the word Jabari Parker used after Duke were upset 78-71 in the first round of the NCAA Tournament by No. 14 seed Mercer.

But could that defeat stop the 19-year-old Parker from becoming another great college basketball one-and-done player and move into the NBA ranks next season?

"I don't know what I'm going to do," Parker added after the loss.

One thing is certain… there will be a lot of people talking in Parker's direction telling him what he should do.

Parker wouldn't be the first big name expected to go in the top three of this June's NBA Draft to decide they don't want to be a one-and-done player in terms of the number of NCAA games he played in his collegiate career.

Oklahoma State's first round loss in last year's NCAA Tournament was a big reason why Marcus Smart returned for his sophomore year.

And there are other reasons Parker may decide against the NBA Draft.

Duke coach Mike Krzyzewski has put together a (Blue) Devilishly good recruiting class for the 2014-15 season, topped off by the freshman class's number one player Jahlil Okafor as well as top point guard Tyus Jones and wings Justice Winslow and Grayson Allen.

Parker and Okafor know each other well with both being from Chicago. And Parker, Okafor, Jones and Winslow teamed up to take the title at the 2012 FIBA U17 World Championship.

There is also still the possibility that Parker completes a Mormon mission, which typically lasts two years.

"I'm told a Mormon mission still isn't out of the question for him," wrote ESPN basketball reporter Chad Ford.

"I asked several GMs about what would happen to (Parker's) draft stock if he declared for the draft and then said he was going on a two-year mission. I was surprised how many of them said they'd still consider him with the No. 1 pick."

Parker is considered by many observers as the most "NBA-ready" of the top first overall pick candidates, which also include Kansas' Andrew Wiggins and Joel Embiid, Smart, Australia's Dante Exum and Kentucky's Julius Randle.

Ford went on to say that Wiggins and Embiid are also considering returning to Kansas - though apparently less likely than Parker returning to Duke.

Of course, another major consideration is money. Not only would Parker miss out on his salary for the 2014-15 season but he would also delay by a year when he could sign his second NBA contract, which usually is the best-paying deal for players in the league.

Then there is the possibility of over-exposure should Parker return for another season of college ball. Scouts will have a second look at him and will try even harder to pick apart his game and determine if his somewhat lack of athleticism and defense issues could be as much as problems.

It would be a chance for Parker to prove any critics wrong. And it would be a chance for a young man to enjoy the gifts of being a college student. It will be the last time that Parker can still be a kid, at least more or less.

Once he leaves the doors of Cameron Indoor Stadium for the last time, he then moves on to the world of professional basketball, with all the advantages and disadvantages that that holds.

Parker has a strong family support system in place and will certainly need them as he ponders this difficult situation and decision.

Far be it for me to tell him what he should do, but if I were asked what he should do, I would say follow the guidance of his own words. Here his tweet @JPiz1 from March 13 - eight days before Duke's loss to Mercer: "a wise fellow told me. Don't be afraid to be "YOURSELF". We do ourselves a favor by being proud of who we are. Just be "you", good or bad."

He should do whatever he feels is right in his heart and not worry about how others will see it.

With so many sides, many will be against it regardless.

Good luck in your decision-making process, Jabari. We'll be ready to talk about your decision when you make it.
