"upside" is obviously one of the most used terms on this site and, as such, i think it would be instructive to explore it in detail. so, the following questions to the board: - how exactly do you define upside? (just to ground the discussion, don't bother if you agree with prior answers) - how do you determine the upside of a particular prospect? is it a function of talent alone, or are other factors taken into consideration? is it improvment of play at certain times? what are key indicators of high upside, or, just as important, low upside?
