please do not flame in the forums. Injuries can happen to anyone, luckely they do not happen every week to evey team.
Doctors can help you prevent them, or at least shorten the time of injury...
The key imo is to not rely on 1 star player in your team.
Look at me, I have 2 players injured, of which 1 is my best and starting SG, still my team manages to perform well enough.
Try to trade a player who stands out too much alng with a much lesser, for 2 guys that are in between them.
That way you create a balanced team, and injury doesn't hit that hard.
They are not your friends; they dispise you. I am the only one you can count on. Trust me.
