Sheesh dude here's some advice; You need to toughen up. This is some internet forum, being so thin-skinned here is unbecoming.
I follow HS basketball, probably closer than anyone on this forum, and to answer your question; of course they do. there's literally examples of it every year. In this years draft class look no further than Josh Jackson, or better yet Harry Giles and Justin Jackson -- Go look at what people had to say about Justin Jackson after he shot 20-something % from 3 as a freshman, or how Giles has been deemed damaged goods those stories would not have the attention they did if they were if they were just some random 4-star kids ranked somewhere from 40-100... that attention was in-part due to 5-star and top-10 status, if you choose not to believe that, so be it. Thats how this poopoo works though, I've been following this stuff pretty closely for about 12 years and thats my take, it repeats itself yearly it's failsafe..
Shabazz was always attacked in HS for his advanced age and being ranked #1, even when he was the MVP of the McDonald's All-American game. Shabazz's pops fanned the flames of this, what I guess could be called age-ism, obviously you're unaware of the whole backstory. I'll fill you in. His father was telling everyone he was a year younger than he actually is for a very long time, and got caught red-handed. There's plenty of articles from 2013 about it. Shabazz decided to remove him from his basketball endeavors entirely before he even got to college because his meddling became counter-productive. So yes, he was wrongly attacked and it was onset, in part, by his father, when he was just a teenager.
There's a bias about age constantly, as seen with Malachai Richardson, who remained underrated mostly because he was the age of many sophomores as a freshman.
