What the hell do you mean by "stupidly overtrained" ?
If a player is trained to such absurdly high levels in a couple of skills as to be unaffordable (and these are generally your monster big men with little to no training in things like handling/passing), then they are stupidly overtrained. You specifically cited guys with $500,000 salaries which I expect was a slight exaggeration, but if it's a player nobody can afford for any real length of time, it's not a player who is well-trained. National Teams of course are delighted to see these guys survive, but the reason that nobody's going to shell out much money for them isn't the 'broken' economy but the fact that they're a disastrous player for any club team to own.
