Alijah Arenas' knee injury, which could potentially keep him out of his entire freshman year, was perhaps the most devastating news coming out of college basketball. It was hard news for his father, Gilbert Arenas, especially when the former NBA player thought that his work ethic had become a curse for his son.The former Washington Wizards player finally addressed Alijah's injury in a video posted on his Instagram account on Tuesday. In his "Quick update on Alijah" post, Gilbert hilariously said in the video that his son got his genes when it came to working hard in the gym."The boy, he just does too much," Arenas said. "He was fine one day and then was hurt the next. These four, five, six months, he should learn how to sit down and rest and listen to his body. Understand that as much training you do, you gotta recover. He realize he got that part of the gene that just wants to work, and he has to understand you can't work four five times a day."Somehow, Gilbert's soliloquy shifted to school, and in the later part, a quick reveal of his wild GPA score."School and all that...like with me, I told him n**** I didn't go to school," he added. "I trained. Back in my day, school was for fools. You should know everybody who got an A on the team, they went to study in the hall, I went to gym. I had a 0.2 and a 0.3. If I go back to school, god damn, I am a freshman he probably got more credits than me."
