Kylan Boswell Shows Athleticism – But a Shaky Shot – at 2026 NBA Draft Combine

In this story:
Illinois’ least-discussed NBA Draft prospect: senior guard Kylan Boswell. With freshman standout Keaton Wagler being projected in the top five and Andrej Stojakovic’s every move being closely monitored, as his Illini future appears to hinge on the NBA Draft Combine, Boswell has slid into the background.
But as a projected late second-round pick, Boswell’s stock certainly will be influenced by his performance at this week’s combine in Chicago. And through the first few days, Boswell has had mixed results. Listed below are his official measurements:
Key takeaways from Kylan Boswell’s official measurements

Hand length: 8.0 inches
Hand width: 8.5 inches
Height: 6-foot-1 1/4
Wingspan: 6-foot-7
Weight: 226 pounds
Standing reach: 7-foot-11
The head-turner: Boswell’s height. The majority of the college hoops world – including we at Illinois on SI – thought Boswell was quite generously listed at 6-foot-2, with the assumption being that he might not even crack 6 feet without shoes.
Checking in at 6-foot-1 1/4 is a huge win for Boswell. A wingspan of 6-foot-7 is also a massive bonus, as is his stocky 226-pound frame – but only because it clearly doesn’t hinder his athletic ability.

Boswell’s vertical explosion – which was rarely displayed with the Illini – was showcased on Tuesday in Chicago. He impressed in both the no-step vertical and the maximum vertical. His lateral agility was above average, as well. Although these results are favorable, it likely didn’t move the needle very much.
Why Boswell’s shooting results at the combine may harm his stock
Spot-up shooting: 12-for-25 (tied for No. 46)
Off-the-dribble shooting: 14-for-30 (tied for No. 60 out of 68)
3-point star drill: 12-for-25 (tied for No. 35)

Bsowell didn't have his best day shooting the rock in Chicago. He finished in the bottom half of each drill. On one hand, Boswell shot 27.2 percent from deep over his past two seasons, so his combine performance wasn't exactly a shocker.
On the other hand, the hope was that Boswell – who did shoot 38.2 percent from long range over his first two college seasons, at Arizona – would get hot and win some scouts over as a result. His stock likely won’t slip from his shooting performance, but it was undoubtedly a missed opportunity.
Fortunately, with the scrimmages taking place on Wednesday and Thursday, Boswell gets another chance to prove himself as a shooter while ideally flexing his strongest muscles (on-ball defense, slashing and facilitating).
