They look robotic because they are still learning... They are still thinking while they're making their moves. 95% of the league would look stiff at this point.... That won't change until they do the moves to the point that motions become natural. Just like someone who can't dribble with one hand... When they're learning to dribble with that hand its gonna be choppy and loose. But once their bodygets used to it, those muscles will become stronger and get used to it, and it'll all become more fluid.
They'll both be fine if they can retain it and continue to practice... At some point they won't even have to think... the right moves will just come naturally. The best players don't think before they make their moves... They just do it subconsciously
you have a good point about the first part on why they look so robotic. but its not true that the great players do counter moves completely subconsciously. like i said in my above reply. they can practice all they want. and if they dont have the hoop IQ to remember when to APPLY these moves. it wont matter that they know them thru and thru and can perform them smoothly if you called out each move . some guys just never learn WHEN to use the counter moves. it wont come natural for some people EVER.
