A number of people have been commenting most recently on the worthlessness of the Cub young players such as Matt Murton and Ronnie Cedeno.   The comments, particularly those directed at Murton, to my mind, seem ill chosen because they represent an unrealistic set of expectations for a good major league player at an early stage of their career.  So I ask these folk the following question:

Exactly what standards would a young player have to meet in order for the young player to be considered anything other than a failure.  I don't want "creepy eye" answers (ie the player has to "look" like a player because such answers are of no value.  I want an objective test - such as hit .375 with a slugging percentage of .650 (which would appear to be the Dusty Baker minimum test)
