NBA Draft Combine 2019: Most Impressive Measurements from Chicago

The NBA Draft Combine gives many of the top players in the country a chance to scrimmage against each other and boost their draft stock.

However, it also provides teams with a chance to check players' heights, weights and results in athletic tests and drills.

Players like Zion Williamson, Ja Morant and RJ Barrett, who are expected to go with the top three picks in the draft, did not take part in testing.

However, there were still notable numbers from the combine, provided by Zach Brooks of NBC Sports.

Start with center Tacko Fall of UCF, who nearly led UCF to an upset over Duke in the NCAA tournament. Fall's size was intimidating in that game, and he was measured at 7'5 1/4" while wearing shoes and weighed 289 pounds. He has a remarkable wingspan of 8'2 1/4" and a standing reach of 10'2 1/2", meaning the tips of his fingers can reach the top of the rim when he is standing flat-footed.

Bol Bol of Oregon also makes an impression with his size, although he is not quite as big as his father, former NBA player Manute Bol.

The younger Bol showed solid potential while playing with the Oregon Ducks in nine games before he injured his foot, though his measurables were not nearly as impressive as Fall's. Bol measured 7'2 1/4" in his shoes and weighed in at 208 pounds. He has a wingspan of 7'7" and a standing reach of 9'7 1/2". Like his father, Bol is quite thin. While he can block shots and outreach opponents for rebounds, he is going to struggle in physical battles for the ball.

Brandon Clarke of Gonzaga showed off well at the combine with his leaping ability and quickness, but his wingspan was quite unremarkable. Clarke is 6'8 1/4" and weighs 207 pounds with a 6'8 1/4" wingspan and 8'7" standing reach. Clarke had a standing vertical jump of 34.5 inches and a 40.5-inch maximum vertical. He also had a 3.05-second shuttle run and a time of 10.6 seconds in the agility test, per CBS Sports HQ.

Guard Jarrett Culver of Texas Tech measured 6'6 3/4" in his shoes and 194 pounds, with a wing span of 6'8 1/4" and a standing reach of 8'4 1/4". Culver is expected to be drafted in the first half of the first round.

Forward Jaxson Hayes of Texas is also considered to be a first-round draft choice, and he measured 6'11 1/2" in his shoes and weighed 219 pounds. Hayes has a wingspan of 7'3 1/2" and a standing reach of 9'2 1/2".

Duke forward Cam Reddish may not have been as dominant as Williamson or Barrett during the 2018-19 season, but he still has impressive ability and is likely to be drafted within the first eight picks. Reddish is 6'8" in his shoes and weighs 208 pounds. He has a wingspan of 7'0 1/2" and a standing reach of 8'9 1/2".

Carsen Edwards of Purdue led the Boilermakers deep into the NCAA Tournament, and he averaged 24.3 points per game this season. Edwards is 6'4 3/4" in shoes and weighs 199 pounds with a wing span of 6'6". No measurement of his standing reach was made public.

Guard Nickeil Alexander-Walker of Virginia Tech measures 6'5 1/2 in his shoes and weighs 203 pounds. He has a 6'9 1/2" wingspan, but his standing reach was not made public.

The NBA draft takes place June 20 in Brooklyn, New York.
