No, it should be for all ages, with the posibility growing exponentialy by age, but nevertheless there is a real posibility that Greg Oden (a very young player although his look...) will have an injury that will change is skill for good, or Brandon Roy (27 yo player) will have one that will end it.
I'll repeat...
No, I´m saying we need something to end player´s careers, other than manager´sAnd after all your realism claims, you should join me in the point that a career ending injury becomes more likely the older you are. You might recover form a torn ACL if you´re a young gun (even in 4-5 Buzzerbeater weeks), but you may not come back if it´s your third and you´re already 33.
