I ran some statistics on this about 5 seasons ago?
I found strong correlation between some stats, but low correlation between other stats.
I compiled box scores from about 20 teams and compared to the draftees skills sets.
Steals and OD had strong correlation
So did Assists and passing
So did FGM and IS
and PTS and IS
TR and Rebounding
HOwever things like 3pt FGM vs JR, correlation was low.
Handling and Driving were not correlated to anything.nor was stamina, FT's
So essentially i came to the conclusion that its generally 'logical' relationships between box scores and you have about a 70% change of it being logical.
But its also relative to the rest of the draftee's. 54 points vs 30 points, IS is still probably only going to be Respectable.
