Bargs has defended Zach, Marc, Booz, Amare, and the like routinely in his career. He is just bottom of the barrel literally in the league at any help defensive situation involving pick and roll created help defense. You can put him one on one with any big, his whole stay as a raptor, and you won't destroy him until you make him react to the other 8 guys on the court besides him and his man. That and his lack of rebounding which is about the fact he doesn't box out mostly ever as Synergy points out he boxes out for his career less than. 20% of the time on average (career high was 09 which was. 22 % in all rebounding scenarios). Something so simple as not boxing out costs him boards, which if he got, he would be thought of as good or better than David Lee (bad in both man and team scenarios but better on the glass and offensively) for example.
A guy like Harden for example is one of the worst defenders at the league no matter who he's playing role player or star, and his help d is also one of the worst in the league. The gifs that are made of him on D being a joke are funny. He just has a rep of flopping but not being "soft euro" unlike. Andrea.
I mean people act like this isn't the norm for Harden who has gotten lit up historically his whole career and gives up almost 2 points per attempt on man d to his matchups. Harden has a plethora of defensive clips like that on their to illustrate his problems in their library. He is truly a one sided player but people ignore it
