TP for putting this together. I think we'll see him getting to the rim next season.
One weird anomaly I noticed on the measurements list you linked is that Corey Joseph has by far the fastest agility and by far the slowest sprint. Huh? Was the guy with the stop watch drunk that day?
I think this just goes to show that the drills really don't mean much. There is so much random variation--for example Doug McDermott purportedly jumped as high as Blake Griffin, to give you an idea. I don't trust the BF% measurement either, it's a measure of your body's conductivity to electrical current which is only roughly correlated with BF%, but it's probably a better test to just look at a dude and see if he's ripped or not.
i read somewhere that the Rock is considered obese. I won't look too much into this. He may benefit from losing 5-10 lbs, but I wouldn't go too far like Sully or Kelly (Sully needs to lose more, or Kelly needs gain more, or whatever)
I think he is in the right range.
The Rock is overweight based on BMI, which simply takes your height and weight and spits out a number. It completely ignores how muscular you are, so body builders are typically in the obese range. (The measurement itself is not a problem if used as intended [to classify large populations], but when it gets used on individual people it's useless)
Body Fat %, on the other hand, is impacted by things like how hydrated you are, so it's hard to really say how accurate it is (assuming its based on bioelectrics)
