What is Illinois Guard Kylan Boswell's NBA Draft Ceiling – and His Floor?

In this story:
A five-star recruit coming out of high school, Kylan Boswell has long been viewed as an NBA prospect. But after two seasons at Arizona, there was work to be done (even after Boswell shot 38.2 percent from long distance over those two years).
What would his role be at the next level? Was Boswell’s facilitating, shooting and on-ball pestering enough to make up for his lack of height and vertical pop? And, most importantly, would all of those skills translate to the league?
Well, with two more seasons of college hoops under his belt, Boswell has shown it all. At Illinois, he wore every defensive hat imaginable, not just guarding but locking down every position under the sun. Offensively, he was arguably as versatile – and every bit as willing to take on any role asked of him.
He could orchestrate offense, get downhill or knock down shots from beyond the arc. Most importantly, he could slot into the lead guard position or play off the ball – and still be a valuable playmaker in the latter role.
Boswell proved that he could be a secondary creator and an elite defender – and he did it on a Final Four team. Finally, scouts had seen everything they needed out of Boswell … almost. Because although he could hit threes, he wasn’t exactly efficient. That jumper, which had previously been a weapon, became a weakness with the Illini. He shot only 27.2 percent from behind the three-point line in his two campaigns with the Illini.
So where does that leave his NBA stock? League front office may be a bit confused – which means Boswell’s stock remains volatile. His ceiling and floor are flexible even with his college hoops career wrapped up and the draft just a month away.

Had Boswell been near the top of the charts in combine shooting drills last week in Chicago, he would have flown up charts. But he wasn't. Encouragingly, though, he did go a solid 3-for-9 (33.3 percent) from deep in scrimmage action while adding 3.0 assists per game. And Boswell also measured well (the head-turner was that he checked in at 6-foot-1 1/4 without shoes) while impressing in athleticism testing.
Still, the combine was mostly a wash for Boswell, all things considered. His stock now relies heavily on his performance in private workouts and team interviews.
By all accounts, Boswell should win over front offices in his interviews. He appeared to have been a class act as a teammate and leader at Illinois, and he is likely realistic about his role (at least initially) at the next level – both of which could be sticking points for other second-round prospects.
In the end, it all comes down to how much a particular team values Boswell’s game. He may not even be on the board of one squad, but he could be an ideal option for another team in the second half of the draft. Given that it’s likely his name will remain uncalled until the latter half of the second round, even Boswell’s biggest fans among NBA shot callers probably won’t see fit to pluck him off the board any earlier than No. 45.

Now, we don’t want to send any negative juju into the universe before Boswell completes all his pre-draft workouts. But, theoretically, if he continues to struggle with his shot, his stock may not improve – and he’s already on the outer edge of the second round.
Even with that in mind, though, it would be a surprise if he weren't able to boost his prospects in interview sessions. And his primary abilities – defense and secondary playmaking – aren’t fully displayed in private workouts, which teams certainly recognize. So, at this point, his stock isn't likely to tank.
And, again, all it will take is one team to be intrigued – and a player with Boswell’s traits undoubtedly has quite a few fans in the league. So regardless of how the next few weeks unfold, expect Boswell to hear his name called in June.
