Pls read the news again:
As has been frequently discussed for several seasons, we would like to limit the effectiveness of short rosters, used by many teams across BuzzerBeater. We will be looking into tweaks to player stamina effects on late game performance and possibly an age based increased probability of injury for players playing full matches, where older players will be affected more, while draftees won't feel the change at all. We will be testing these changes during the season, and will be seeking your feedback on what the best solution will be.
This sentence in bold seems to be crucial. It depends on the age of the player.
I can well imagine that an algorithm is used that strongly takes age into account. The older the player, the higher the probability of an injury. Wasn't there a mathematical function for that? 18yo=0% (probability of injury), 19yo=0.001%, 20yo=0.01%%, .... 30yo=5%, 31yo=7%, 32yo=10%, 33yo=14%, etc...
What I want to say is: The chance that a player between the ages of 18 and 30 will get injured if he plays 48 minutes is not too big.
