the article you linked to is complete trash. particular the paragraph about these players knowing what they are doing and fines should be implemented. sure on a catch and shoot you can intentionally slide your foot under if you are dirty, but the play in question is not even close to that type of play.
williams does a step back jumper after a very hard drive/pull back. kemba is reacting by lunging forward after the fake and trying to challenge the shot. if he can do all of that and STILL have time to consciously put his foot under his landing area, why doesn't he just strip the ball on the way up because his reaction times are that good? complete garbage hypothesis in that article.
Jalen makes so many stupid comments which are very. "Out there". He simply does it to draw attention so forms like this discuss him and increase the hits on the site. He is the same guy who said MJ is gonna come out if retirement.
Everyone do yourself a favour and ignore this guy.
