It's fact that SB didn't work in seasons before season 25 (or something like that, I don't remember exactly when SB changes was implement). SB was practically worthless in that time. Few managers discovered it and there were created 400k monsters played in successful NTs. (fwiw I saw few NT games).
Then we had change. First element of change was salary, SB became cheaper. However salary has no impact on GE. For finances still it's cosmetic change. I think high-end center, with SB+5 than typical, will have new salary smaller by 5k in comparison to old formula. Of course for other positions effect is smaller and for guards there is no gain in comparison to old formula.
Second element of change was little more impact of SB in GE. However "practically worthless" strengthened by "little more impact" still is practically worthless. It's easy to find successful teams, which defence makes opponent cries, and which have typically 0-2 blocks per game.
