Yes. Did you. Why do you think he really does not play in 2nd half of any games?
Hits deck because he is 6 foot and 90 pounds.
He makes too many mental errors at this point. Physically he looks like the quickest kid that has ever lived out there on both ends, but he needs to catch up to the speed of this level mentally. His skill set also doesn't allow him to fully utilize his speed at this point.
He battles for rebounds, he hits the deck for loose balls, he's always in motion...effort will be the least of his problems this season. Maybe if/when he gets better all around as a senior and is scoring 18 ppg that could be an issue.
