Maybe he's trying to say its hard to succeed with a training-to-sell based model then it would be in an inflationary market, as compare to a training-for-keeps model. If you're training for other teams you won't get much return. If you're training your players for keeps to win and have a team built around that training you will see dividends in revenues derived from on-court success (promotion, arena).
If so, that's true. Though I don't think this is bad. If winning and promoting is the best way to make money over training-selling then that means more teams will focusing on competing. I'd much rather have a game were the best way to succeed is success on the court over success off of it.
For me it's hard to separate this issues from Hattrick, a game where it's easier to be financially successful by training and avoiding promotion. It's the single biggest reason I've given up on that game.
