So your first argument cannot be correct.
No, my first comment (not an argument) is correct.
My second comment was pretty bad because I did not make clear to what exactly I was referring to. The effect I meant is the rival effect. There is no negative impact in acquiring a rival's player when compared to acquiring the player of some other team.
Turn facts it as much as you like - a player who is part of the club (equal a drafted player) will always get more attention from his fans, than a player with the same skills, that played for the club the same amount of time.
A promissing potential straight out of the draft will get more attention comparing to one with a current better skill.
This attention is good, if that player is getting minutes and evolving, and bad if he is being thrown away or not used.
