I agree defensive stopper/effort type of player is much needed!
The days of High level, versatile player, in High School, who love the intangible work, such as Lock Down defense, Rebounds and all out hustle is dead. Mixtape/Highlight tape, has killed that mindset. For high school kids, It's all about training to put the ball in the basket. These days, Every kid in the country that plays basketball has a highlight tape of them on offense. You never see defensive Highlight tapes.
Top tier High school talent tend to not work as hard on defense because they are usually just better than everyone. So bad habits develop and Coaches don't break them from the bad habits. The better you are as a Player the less demands of you on defense. You see this all the time with the top players.
Then these kids struggle understanding the demands of fitting into a college roll, because they're so used to having everything running thru them. Those struggles tend to fall on the defensive side.
High school game has to do better.
