With the 2017 NBA Finals officially behind us, it's now time to fully turn our attention to the offseason. And all the fun there begins with the NBA draft.

This year's class is a strong one, led by two point guards who were ultra productive in college in Markelle Fultz and Lonzo Ball. After them, the lottery is packed with potential. Players like Josh Jackson, Jayson Tatum, De'Aaron Fox and others could all do wonders for a franchise if they hit their ceilings.

But what brings us here today are the guys a little further down draft boards, players who may get taken in the first round, but certainly aren't a lock.

Profiles of some of the most interesting fringe first-rounders will follow the mock draft below:

Frank Jackson

Thanks to a strong showing at the combine, where he posted a 42" max vertical leap and outclassed most of the five-on-five competition, Duke guard Frank Jackson was flying up draft boards before foot surgery put the hype on hold.

"Frank decided to have the surgery now so that he could be healthy in advance of the NBA training camps,” Dr. Erik Nilssen told The Vertical's Adrian Wojnarowski. "He will be able to resume full workouts in late July. His surgery went very well, and I expect him to have a great NBA career."

The "great NBA career" part of that last sentence was looking more and more possible for Jackson as he went through the predraft process. He was showing off the athleticism that made him a top-20 recruit (per Scout.com) before he started his one year at Duke. And it was starting to feel like people were forgetting his lack of production there.

Jackson was understandably underwhelming as a freshman, averaging 10.9 points and 1.7 assists. But his situation lent itself to suppressed numbers. He entered a program that was bringing back two of the nation's most productive guards in Luke Kennard and Grayson Allen. Something of a backseat was only natural for Jackson. And it may actually help him at the next level.

As a late first-round pick, Jackson likely won't be much more than a role player off the bench. He's already used to deferring to bigger names.

Jordan Bell

In an episode of Locked on Fantasy Basketball with Josh Lloyd, Sporting News draft analyst Sam Vecenie opined that Pac-12 Defensive Player of the Year Jordan Bell may wind up being the best this class has to offer on that end.

During his three years at Oregon, Bell averaged 3.6 blocks and 1.7 steals per 40 minutes. And at the combine, he posted a 38" vertical to go along with the fourth-fasted time in the shuttle run. Not bad for a 6'9" player with a 7'0" wingspan.

There are plenty of questions about his offensive game, but at the end of the first round, measurables like that and a defensive reputation to boot are hard to pass up.

Derrick White

If Colorado guard Derrick White wasn't already pushing 23, there's a good chance he'd be much higher on most draft boards.

He's a 6'5" combo guard who can run an offense, distribute the ball (4.3 assists last season) and shoot it too (40.1 percent from three).

"Far more than just a shooter, White is also a crafty scorer inside who converted 45 percent of his floaters and 62 percent of his finishing opportunities in the half court last season," DraftExpress' Matt Kamalsky wrote. "Though he doesn't play above the rim often, unless he has a head of steam, he's a very creative scorer around the basket who makes shots from difficult angles contorting his body around defenders or stopping short and dropping in floaters with soft touch."

That craftiness (and more) will be needed at the next level. But against second units, White might be able to develop into a solid floor general who can get his when he needs to.
