Maybe this is what the game (or most appropriately, the company) wants users to do; it make managers believe that their players are no more good and hence 'forces' the manager to buy other players,
Have you wondered why many scout list players performed well in the first season and then performed badly in the following season despite still having very good displayed quality? There is a much better chance for managers that buy many scouts' list players to buy those players from that list again, and hence the probability of such managers to spend a lot of tokens is more compared to the other managers.
It is almost sure that some things are programmed in this game to occur as such, most probably mainly for the company to benefit financially.
I guess it can be a simulation of real life ... some players may be on a bad run, a few games break and they will return back to form. That's what happened to JP.
