First of all- My sincerest apologies. A) I honestly didn't understand the original post to which I replied.
I neither had nor have any intention of sounding like Kozlodoev.
I agree with your analysis in the final paragraph. Training for me has always been more about improving my team than selling my players. I am not addicted to seeing pops. I have always mostly relied on ticket revenue so I paid the extra coin for a level 6 PR guy. My merchandise revenue went up drastically over the level 10 guy ( and subsequent level 5 after he was retooled)I had before. Still, the "drastic" rise was enough to pay a week's salary for my best player, which is about the salary of your backup towel guy. This 20k isn't gonna make or break me, but I think it will eventually recoup the 240k I paid in the dizzying days of the new staff arrivals.
As far as trainers, I looked today and a level 6 was $800,000 with an hour left to bid, a level 5 was $300,000with about the same, and a level 4 was 6 grand with three minutes left to bid. I think those prices are a bit lower than a month ago, and by the time my current level 5 trainer's salary begins to bug me I think they'll be down even more. I certainly own't hesitate to get a level 4 if they aren't, though.
Once I scored a basket that still makes me laugh.
