Guessing makes it sounds as if it's just picking possibilities out of a hat. Scouts will assign a different ceiling for a player, it's an arbitrary system based on the opinion and knowledge of the scout. Not recognizing their efforts and intelligence towards a logical conclusion (ceiling) would be similar to saying teaching methods while different are basically shots in the dark as far as effectiveness and a guess as to whether or not it will work with kids. It's very important to grade their ceiling, especially kids that haven't fully developed, the younger you go, the more important it becomes compared to where he is in the present. If you draft a HS kid, you're more concerned with how good he'll be 5 years from now moreso than how good he is now and if he has the tools and tangibles to get there. Players are mostly graded on their tools as well as the intangibles. Ceiling (projection tools) factors greatly in drafting a kid as did his signability and intangibles. I don't know why Farnsworth was drafted when he was, it went to some Georgia agriculture school so exposure could've been limited, he might not have shown anything beyond a straight FB, or his FB could've been topping at 90 and straight and been reworked once drafted. Hard to say why with so many potential reasons. You are absolutely right. Good scouts can make a difference just as good teaching practices can make a difference. However, I think good player development people are probably more important. Nevertheless, potential or ceiling is an unknowable, but I certianly would want good people to help pick talent. Be that as it may, when I hear people here write about a player like Jake Fox, Ryan Theriot or Angel Guzman's ceiling I cringe.
