Watching some more footage of Aldama - he actually does seem pretty quick on his feet, agile, nimble out there, seeing some clips where he's able to defend well out on the perimeter. I know it's lower competition level, but talent is talent.
This play you have to be impressed with the footwork and how fluid he moves on the court and handles the ball and shoots it. Very smooth, step back 3, looks like Dirk a little bit.
Next video here, really like the play at 3:10, a move like that for a 6'11" dude is very impressive, especially at age 20. Has a defender all over him, makes a hard drive, then creates some space with a nice hesitation move before finishing strong at the rim with left hand. Overall in this video he looks pretty quick on his feet, mobile, agile and has decent lateral quickness on D, closes out on shooters well, some good help D. At 4:56 mark, looks like Nowitzki on this play, faces up from the wing, tries to drive on defender, then backs him down in post, turns out of the post and hits a tough fadeaway jumper with hand in face from 18-feet, nice! Another play that you simply don't see 6'11" dudes make, especially ones who are only 20 yrs old. At 5:49 really smooth on the catch and shoot 3, good footwork setting his feet and squaring up prior to the catch so that once he catches it he can go right up into the shot. Again, you just don't see this stuff from 6'11" dudes, especially ones who are only 20. 6:33 mark Aldama's man has the ball in the corner - Aldama defending him tight out on perimeter so the offensive player tries to drive on Aldama, but Aldama does nice job moving his feet and sticking with his man, doesn't allow his man to get a look at the basket and has to kick it out to the corner.
Last video, really like the play at 1:31 mark, you see him get ball in corner, backs up to give himself some more room to operate with through the legs dribble, then drives on his man, faking one way before leaning in the other way, goes up with shot and draws foul - nice skill level for a 6'11" kid, especially one who's only 20. Really nice play at 2:19 mark, ball fake to try and get the defender off-balance, then a hard drive to the rim, which gets the defender leaning towards the basket cause the defender thinks Aldama is taking it all the way to the rim but then Aldama stops on a dime and hits the step back jumper around the foul line, really smooth, good footwork, good skill level for a 6'11" dude, especially one who's only 20. 3:11 mark faces up from perimeter, looks to take his man off the dribble. Again he likes that ball fake where he fakes a cross court pass, he really sells it to - which allows him to get a step on his defender when driving, from there he accelerates to the rim for a strong finish - showing nice combination of size, skill and quickness - very fluid for a 6'11" dude, especially ones who's only 20.
This guy could be a steal at 45. Oh yeah and word on the street is he's actually now 7'0" (with a 7'2" wingspan).
