Let's focus on one thing because it becomes a repetition of the same point over and over without relating to what I wrote.
Let's repeat what you've wrote (in a sence):
The players does not work for this season, they prepare for next season, and trying to get better salary.
The PR is preparing for next season, not for current. In case they will do a better job, they will keep their job.
Is it just me but or that it sounds the same state but different conclusion?...
It's a funny fact that YOU are constantly bringing the same exact answer to whoever tries to make you see how much you're wrong...
Again: the players train for themselves as much as for the team where the PR only works for the team. You get the difference don't you? Tell me you do please...
I guess that the players during season keeps playing for themselves too - next seasons contract.
While their trainers will not show better performane next season due to the practice they are carying on, and that will not affect how they will be presented as trainers...
From the second it becomes silly to pay someone for a period of time, it means that the design is wrong.
Why would a team pay for a PR / Doctor (and/or trainer in a sence) during the off-season [At least when buying a new is cheaper than just keeping current staff]?
There is no reason and hence the market, any market, will make this payment removed.
It is just the way a market works.
