I think there's a misunderstanding here. Just to be clear this is the way it works:
You will get the chance to scout again during the offseason and your scouting points from this season will still be available for this offseason. So once the offseason starts you will be able to spend the rest of your 10,000 points you had before the playoffs Notorious.
You can't rollover scouting points from this draft class to next season though. But from what I've heard you barely have enough scouting points to effectively scout for one draft class so rolling them over doesn't make sense anyway.
