Maybe it me but

This added element of excessive staredowns and reckless demonstrative
shit talking that I'm seeing in prep/AAU ball will get you the hands
by an old school type of hooper or atleast a strong foul.

It didn't seem like Chriss did a lot but he had the staredown and
appeared to say something while Serge was on the ground and sometimes
thats all it takes depending on whose involved.
