Ok, I got it, but still this is not too logical... this should be the best game in the world... then what is the meaning of having the 48 minutes for training one position, if the game is only 43 minutes...
i believe the bb was scared that people will arrange scrimmages, to get the perfect training minutes without the risk of an injury or fouling out.
I hope they will arrange an scrimmage against an bot like rooster in the future.
PS: You only lost minutes when you combine starter and backup, starter and reserve is possible to get 38 minutes.
