What is your suggested fix? FYI, in case you are questioning the fact, Bronson sold for 500k more than a nearly identical player the day before and 1M more than a similar (but higher-salary) player within the same week: bitching about this is well justified.
Deductive reasoning time!
It's a fairly well accepted fact that home country NT players cause a merch bonus equal to 15-20% of their salaries when they play serious minutes. So, for Bronson, that's $45-60k per week.
My experience as I've converted from mostly foreign to about half and half suggests that baseline merch is also improved by having US based players. My baseline merch has gone from ~10% of team salaries to ~15% of team salaries, and it's my understanding that Machines (darykjozef) is near 20% in my league, without any NT players (darky, please correct me if I'm wrong). So, that data seems to suggest that just being a US player causes up to 10% of their salary in merch bonuses, or an additional $30k per week for Bronson.
So, depending on how you want to estimate, Bronson pays back his extra transfer cost compared to a foreign player at a rate of $45-90k per week. At $500k extra cost compared to a "nearly identical" foreign player, this implies a payback window of 6-12 weeks.
So, it seems logical to me to conclude that if you think a $500k extra cost is too much to buy Bronson instead of buying foreign, then what you're *really* saying is that, even for an NBBA team, a monster guard isn't worth keeping for a full season. So, if that's the case, how are we ever supposed to expect that our monster players are going to stay in good GS? Should we really sink all of our eggs into a strategy that apparently will only pay out if we can get the entire NBBA to make a gentleman's agreement to be salary inefficient and lug around NT monster players? (And simple game theory points out why that will be rare at best -- such a gentleman's agreement is basically a Prisoner's Dilemma with no enforcement mechanism between players, so the players should all be expected to "cheat" and avoid the monsters).
