Although not highly ranked coming out of high school (where he underachieved in his one year at Arlington Country Day in Florida), a strong performance for Spain in the 2014 FIBA U18 European championships made Yankuba Sima a sought after collegiate recruit. He ultimately chose St. John's over Maryland, Louisville and Baylor, who were also in the recruiting mix at various points and to varying degrees. After Chris Obekpa left the program, Sima was thrust into the starting lineup from the onset of his freshman season, where he stayed for most of the year on his way to averaging 12.3 points, 9.9 rebounds and 3.9 blocks per 40 minutes.

Still very much a raw prospect, Sima has NBA potential based on his physical profile, but needs to use his sophomore season to improve key aspects of his game such as his intensity level, feel for the game and offensive efficiency. While he was productive in his 23 minutes per game, he wasn't very efficient with a 48.3% conversion rate on two point field goal attempts and a 48.7% true shooting percentage. He is quick off the ground and is a capable dunker around the rim, but struggles incorporating touch into his shots at the rim, converting at a mediocre rate relative to players of his size of 53.8% of his shots around the basket according to Synergy Sports Technology.

Listed at 6'11” with a long wingspan, he has the size of a NBA center but needs to fill out his frame as he is listed at just 220 pounds. He does have a frame that can add more muscle and will need to bulk up in order to not get pushed around and be competitive around the rim. NBA scouts will also want to see a higher motor and intensity level from Sima as he has a tendency to drift through stretches of the game, turning into a low impact player far too often.

Outside of his ability to dunk the ball, Sima struggled to make an impact offensively. While he displayed some potential to get open looks at the rim out of post-ups or mid-range jump shots, he was not overly effective scoring in either of these areas. He's not an adept finisher after making a simple move out of the post and his shooting mechanics are a long way from being strong enough to make him a threat from the elbow, as evidenced by the 38% he shot from the free throw line.

A valuable skill for him to add as he goes forward is his ability to score out of the pick and roll. He'll need to do a better job seeking out contact on the screen to spring his teammate before rolling hard to the rim. He's too content to short roll to the free throw line for a jumper where he converted only 21% of his limited sample of 19 jump shots logged by Synergy Sports Technology. Sima can make almost every catch on passes that are in his area but struggles to score after a step or two with a defender in front of him. He will have to find a way to finish over length when he can't dunk or be able to get to the line, as he averaged only 2.8 free throw attempts per 40 minutes.

Defensively, he's shown to be a valuable rim protector by averaging 2.3 blocks per 40 minutes. He's a little reckless in that area, chasing every block opportunity and leaving the rest of the defense vulnerable when he comes up empty. He can get out of control trying to block shots and doesn't go straight up as he leaps up, which leads to quick foul trouble and extended stretches on the bench. Becoming a more disciplined shot blocker will help him stay out of foul trouble and keep him in rebounding position. He averaged a paltry 5.8 defensive rebounds per 40 minutes and will need to quickly improve that mark to show he can help control the defensive glass. He has the size and athleticism to be a better defensive rebounder, but he's always been more productive on the offensive glass and he'll need to increase his defensive output to help his team and show scouts he can fill that role.

Sima didn't offer much as an individual defender as a freshman and scouts will need to see some growth on that end to complement his somewhat limited offensive skill set. He's most likely going to be tasked with guarding post players to maximize his role as a rim protector, but he offered little resistance and was easily backed down by his opponent. When he stepped out to guard the perimeter on switches or pick and rolls he struggled to move his feet efficiently and stay in front of dribble penetration.

Sima looks the part of a rim protecting big man and will certainly be on the radar of NBA teams heading into his sophomore season and throughout the rest of his college career. The 20 year old is coming off a productive summer gaining experience playing for the Spanish U20 national team, the third straight summer he has appeared in competitions for the Spanish national team. He'll look to build on this experience as he heads back to St. John's to show a more efficient offensive game and a disciplined defensive skill set so that scouts can have a clearer picture of his potential NBA role, which will likely take a few more years to fully realize.

-Great frame that will fill out considerably in time
-Long arms
-Solid athlete. Moves well.
-Can set quick screens and roll swiftly to the rim to catch and finish. Reliable finisher when catching the ball on the move in the paint
-Good rebounder. Can go out of area with quickness and length.
-Solid rim-protector. 3.3 blocks per-40.
-Has the ability to step out onto perimeter and stay in front of smaller players
-Gets in passing lanes (1.7 steals per-40)
-Has decent form on jumper. Made a handful of jump-shots at U19s, even an occasional 3-pointer. May be able to develop this part of his game in time

-Not a naturally high-motor guy. Intensity level comes and goes. Will jog half-heartedly up and down the floor at times
-Conditioning isn't great. Tires fairly easily
-Mostly a catch and finish guy offensively. Has poor footwork.
-Doesn't have any ability to score with back to the basket
-Hands are so-so. Will bobble some good passes at times
-Not consistent with jumper yet. Only shot 57% from free throw line. 49% from line at U18s last summer
-More of a center than a power forward offensively, but undersized for the position at 6-9

Outlook: Rebounded from a very poor high school season with a solid tournament in Crete. Lacks elite size or athleticism to be considered a top-shelf big man prospect from an NBA standpoint, but should nevertheless be a difference maker at the college level at St. John's with a chance to get drafted down the road if his skill-level, feel for the game and motor continue to improve.

-Terrific physical attributes. Nice frame. Long arms. Very good athlete
-Runs the floor extremely well
-Very reliable target for catch and finish plays
-Good hands allow him to catch virtually everything thrown to him
-Finishes with two hands easily and emphatically with no running start
-Excellent offensive rebounder (6.4 per-40 minutes)
-Legit rim protector
-Very mobile, can step out into the perimeter on defense
-Shooting mechanics look decent. Made 71% of free throw attempts
-Took a 3, and didn't look half bad doing so

-Skill-level a major work in progress
-Needs to be spoon-fed offensively
-No back to the basket game
-Limited footwork
-Can get posted up because of poor lower body strength
-Still learning to play with a consistent intensity level

Outlook: Looked like a different player compared to what we saw in February at the NIJT Belgrade. Improved structure, spacing, teammates, and team-play helped bring out the best of him. Only 17 years old, still has plenty of upside to grow into as his frame fills out. Reportedly looking to take the college route and will easily be considered a high-major player.

-Very athletic big man with an excellent wingspan and a frame that will fill out nicely in time
-Tremendous rebounder. 15 per-40 in Belgrade
-Excellent timing as a shot-blocker. 5.3 per-40. Legit rim protector
-High energy player who competes admirably

-Very limited offensive player. 6.1 points per-40 minutes shooting 33% for 2
-Doesn't really know his limitations. Settles for some highly questionable shots. No ability to operate with his back to the basket. Shows limited touch.
-Made 25% of his free throw attempts

Outlook: Spanish big man of African descent who appears to be on the college track. Can be a very useful rotational piece for a good college team as he has excellent length, athleticism and timing as a rebounder/shot-blocker. Will need to develop the rest of his game to improve his NBA prospects, but he's only 17 so time is on his side.
