Hi Josef, was wondering when you'd come in. :)
Allow me to digress for a bit. I know the mechanics of salary optimization is like opening a can of worms. It's just so abstract and accurate data is hard to come by, heck the users can't even agree on how the salary-potential-skill axis works. And it is not for everyone, I'd point back to the 'Soft Cap' topic in Global as an example (Yes, I haunt that thread too and thoroughly enjoy the banter flying about).
Back to the topic, the choice to buy a certain player still remains up to the individual managers. If they choose to buy a ridiculously unbalanced 30 year old player with a skill total of 150 allocated primarily on skills that matter least for his position, it can be said that he will not as effectiive as those whose skills are allocated in a more effective manner. And if most of his skills matter least for his position, then it is safe to say that he is being played out of position. If that 30 year old was a Center and most of his skills were allocated on outside skills, I'd point out that he is not actually a Center but more of a SG or a SF.
How the managers choose to configure their teams and players, is up to them. You don't have to focus attention on the fine-tuning details of it. But if someone has spent countless hours experimenting with the side skills and found a killer tactic to synergize them, I'd have to hold my hands up and applaud him for smacking my team with a 40 point difference. And hope to exchange info later, of course.
