Does anyone out there have any idea what the mathematical formula is to determine if a player is overused? I have some regular players with long term injuries and I have the problem of playing them as much as possible in the early going when usage is more lax ,but the other side of the coin is that I don't want to rest them until absolutely needed because I am afraid if I play then late in the year that they will suffer a long time injury that could cause them to miss the playoffs down the road. Thanks in advance for the advice.
