It's About Preparing People, not Preventing Injuries
ACL injuries do not happen in a void. People sustain injuries when their infrastructure is unable to manage a specific set of physical circumstances. To describe the mechanism of the injury without the context of the person and their level/type of sport, is to miss valuable insight. In sport, we prepare the person, to the best of our understanding, to meet the physical demands of that sport. We do not just work to prevent one particular injury; we prepare athletes to navigate the total sport physical environment. By "we" I mean the coaching and support staff -- specifically the athletic development staff. Athletic development (AD) coaches prepare athletes through the development of physical literacy and movement competencies via movement progressions. It is more than strength, power, agility; it is the acquisition of knowledge, skills, abilities and behaviors to manage themselves within the entire sporting environment.

Can you explain exactly how this bar was loaded incorrectly? It looks like the collars aren't snug enough against the weights or is this just crappy training plates that warp (or both)?

If you are going to repeatedly lift < 40 kg from the ground, you should use good 5 kg and 2.5 kg training plates (Hitechplates, Eleiko, Werksan) that hug the collars of the bar and support the weight of the bar when it is on the ground. Good training plates allow the bar to sit evenly on the ground for lift off. The rubber 10 lb plates/plastic 5 lb plates are not structurally sound enough to support the weight of the bar. This is is especially true of the weight is going to be repeatedly dropped or left overnight on the bar. This will eventually destroy the skinny 10 lb/5 lb plates.
Other than that, proper loading of the bar means the heaviest bumper/iron plates are always loaded first, then the lighter iron plates are added in sequential order, with the number side facing out. Weight should always be stripped from the barbell after use.
