I used to play competitive bball and what's saddest about this to me isn't the lack of physical skill (which is embarrassing) but the utter lack of team cohesion or even situational awareness. Near the end one of the defenders sees the oncoming opponent player and then goes to screen their own teammate. Prior to that there's the lack of cooperation in the key. I've never even seen an U-15s team of boys play this incompetently. Just...sad.
