i got crushed for reporting this back when it happened, but i went and watched jarrett allen when he was in HS when my school hosted st.stephens on a night when shaka and his wife were in the building. allen acted like an absolute clown who didn’t give a shit about basketball, his coaches, or the fact that shaka smart and his wife were in the building to watch him. allen got T’d up like three minutes into the game for pegging one of our players dodgeball style, after which he hit the bench where he made himself a huge distraction by constantly and loudly joking around, moving around the bench area, not paying attention to the game, etc. my mom (a coach/teacher currently in her 44th year at our school) and i were shocked at how uninterested and disrespectful he was. to this day she can’t believe he made it to the nba based on what an absolute clown he was that night.
you may also recall that allen really struggled during non conference play of his one season at Texas. he did not show up ready to compete in D-1 ball and only got into game shape around the time the year turned. there are guys in the nba who live to be basketball players. allen isn’t one of them.
