Isaac. Okoro. So far through the first few weeks of the season, Cleveland ranks first in Defensive Rating. Okoro is without a doubt the most physical perimeter defender they have on the roster and his IQ for a rookie is unmatched. Okoro is a difference-maker on the defensive side of the floor and it has made him one of the best rookies in his class. Also, don’t jump when he takes flight. #YMAPAA (via @jimmylongojr / @cavs)
