It was a reference to how many high priced players do you start. It's not normally a problem because F1 might be $550k or less and R1 might be $550K or less so starting 4 mids close to or above $600k hasn't been a problem. But Danger is $660k and Grundy is $700k so there are two of your normal high priced players yet people are still thinking they need their normal 4 or 5 mid keepers who are close to or above $600k. If you go Cripps, Fyfe, Neale or Macrae, Cripps, Fyfe you are now up to 5. Alternatively you might go Cripps, Fyfe which gets you to 4 and then people are adding Merrett, Crouch, Dusty or Bont, Sloane, Zorko to fill up their midfield but possibly picking 3 M8's. I think it's trap to think your midfield has to have a certain look each year. Just as we follow the rookies we have to follow the high priced players as well.
normally I initially think 2 @ $ 700,000.00 + 16 @ $ 125,000.00 which gives me $ 3.4 million
then 12 @ $ 550,000.00
but the last few years the defenders have started higher than that , and like you said you then can get caught in a $ 550,000.00 mid trap.
Obviously then if there are viable mid-price you can then juggle things around.
