I agree the term is used to often but I don't think it is a ridiculous term at all.
Look at Joffrey Lupul, He has missed hundreds of games over the last 5 years. None of his injuries are a recurring issue. It's shoulder, foot, wrist, ankle, back, groin or concussion. You name it and he has been afflicted with it.
Joffrey Lupul is one of a dozen or two players whose bodies simply are prone to injury.
