I actually don't wish it on anyone, I literally just redid my pcl the other week which peeed me off. Not as bad as an ACL unless you do a full tear through but stops me running and affected my aikido. At the end of the day, it is just a sport, not war and these injuries last you a lifetime, mine tore because it was damaged in a motorbike accident in the past. His knee is always gonna be that bit more vulnerable, he has youth on his side but he is going to be compromised because of it. Plus he is good player and not a jerk.
