The answers to this clip we found in the socials of Ksenya Romanyuk provided a lot of reactions, alltho nearly all were the same. Our decision is not gonna be any different.
The green center is illegaly blocking and holding his defender from providing helpside. There is no way you want to let this go, because the tone of your game will change for the worst. So make sure you call this early and firm. One might even argue the way the green center is blocking out his opponent is enough for an unsportsmanlike foul. It is clearly not a normal basketball action.
