Possibly true. The average fan just wants the Phillies to be consistently good, consistently in the post-season.
Of course, to get there, the development of young players is crucial. But does the "average fan" understand what an organization has to do to be consistently competitive? Perhaps not; Solomon_grundy may be correct that the "average fan" is clueless about this cause-effect relationship.
The challenge for the front office is to do what they can to improve the short-term product (2017), to give the "average fan" something they enjoy watching - and to do this without impeding the longer-term plan of player development, which is essential if the club is going to become, and remain, truly competitive.
I don't happen to think that this has to - or should - involve bringing in "names" - players the average fan will immediately recognize, because they've been banging around the league for years. I know that some (many?) fans tend to focus on such "names," because those are the only players they know about. But we've seen plenty of evidence that an "unknown" player can become very popular with average Phillies fans, relatively quickly. Chooch? Victorino? Odubel? All they have to do is perform for a while.
The Phils aren't going to sell a bunch of season tickets this winter by hawking Tommy Joseph - any more than they could sell season tickets two winters ago promoting their Rule 5 pick, Odubel Herrera (Who?!). But if Joseph hits 40 HR in 2017...he stars on the winter tour next winter, eh?
