The Ravens have lost more starters than we have.
IMHO, this is part of the fallout of not ha ing hardly any padded practices anymore. People are building their muscles for gym and straight sprint exercises mostly indoors. Then they get into full exertion football activities, where every step includes rotating the joint in addition to the flexion/extension, and lots of start/stop behavior, and the rest of the body, like the ligaments and Achilles, just aren't ready for the stress. If we eased I to it with actual padded play, actual tackling, etc, I think we would have less of these types of injuries.
And I realize I'm in the minority here, but mandatory knee braces would prevent a lot of those knee injuries.
