Getting dunked on is part of the job of the rim defender. He uses his length to try and prevent a quality shot without foulin, sometimes because he is a tiny bit late on a rotation or the attacking player gathered enough momentum, he can't quite affect the shot and gets a big dunk hammered on his face. C'est la vie. If Gobert ends up in that list I am all for it, it will mean he had a long and productive high caliber career.
To Rudy being dunked on 3 000 times, hip hip ! Hurray !
