Agreed and you've been on forums enough that you know I proposed several times changes to both sub patterns and, more recently, ST depletion coefficients, precisely to address teams like the B3 guys and even some in other leagues (including the EBBL) having a drop in salary of over 100k between the 5th and 6th player on the roster. We're back in a situation where people can buy mid season or close to the playoffs because...you don't need to have a proper rotation with 8 players, you just need 5 players as long as they have high enough ST.
On topic, Strictly Follow the Depth Chart would also produce the same result if 5 players are set as Starter/Backup/Reserve and there is no garbage time (which was the case here). The 2 extra players were there just as insurance for injuries and foul outs.
