the players whove never played have the highest potential
Players who didn't play a lot, didn't have the opportunity to disappoint. Kean has played a lot and he is a known entity. That is why there was an outrage when we sold a Kean who still hasn't disappointed for 27-28 millions some years ago, and few will complain if we sell him today for the same amount.
Perhaps naively, but I still believe that the folks who are involved daily with the players, have the ability to more or less successfully predict how will these players develop. Like I have shown in Rovella's thread, we aren't known for selling youngsters for less than what their potential ability is. As a matter of fact, we've made very few mistakes, and a lot of correct decisions. That is why I refuse to be angry if someone inside the team decided to sell a young player for 5, 10, 15 or 20 million. I still choose to make the educated guess that these people have the necessary insights to accurately gauge a player's worth, and predict the players' developmental trajectory over the ensuing 5 to 10 years.
