The 2018 NBA Draft order is nearly set. Now, it's up to the prospects to determine where they will begin their professional journey. Arguably their best remaining opportunity to improve upon their stock was at the NBA Draft Combine, which began on Thursday, May 17. Nothing will replace their game tape, but strong performances this week could shoot a prospect up draft boards. These are the players who did the most to help their stock on Day 1 of the NBA Draft Combine.

SG Grayson Allen, Duke

Allen is infamous for his extracurricular activities on the court.

His combine performance should remind scouts that he brings a different value to the floor as well. Allen recorded a lane agility time of 10.31 seconds, one of the best in history according to ESPN. See, he's more than just a spot-up shooter at the next level - he's a real athlete and proved as much at the Draft Combine.

C Mohamed Bamba, Texas

Bamba was already known to be one of the longest players in this class. He spent the Draft Combine reminding executives of that fact.

Bamba topped current Utah Jazz star Rudy Gobert for longest wingspan measurement in the history of the event. Some team will take a chance for him based on his size alone - based on Gobert's early career, it's not a bad bet to make.

SG Josh Okogie, Georgia Tech

Okogie is more of a hidden gem entering this draft.

In fact, he could return to school. But his performance at the Draft Combine suggests otherwise. His wingspan (7 feet) exceeded his height by eight inches. Okogie impressed in the shuttle run and vertical as well. He was considered a fringe prospect before, but he's playing himself on to draft boards.

C Jaren Jackson Jr., Michigan State

He's raw, but he can do it all. He's a modern NBA big man: tall, but with an ability to stretch the floor on offense with some three-point shooting. At the Draft Combine, most of the emphasize came in regards to the former attribute. Jackson had one of the biggest hand lengths, wingspans, and standing reaches among the other prospects. Bamba better watch out - he has competition for the first center selected.

F Michael Porter Jr., Mizzou

If nothing else, he acquitted himself well in front of the press. Some will say his comments about being the best player in the draft class come off as cocky... and it does. But you have to remember that he was a consensus favorite to be the top pick in the draft heading into this season, when he lost nearly his whole year just two minutes into it. A back injury like his could make a player lose his edge. Not the case for Porter, though.
