Discussion Question: What Does the Hiring of “Experienced” Managers Mean?

Call them experienced, call them the better option, or call them old.  Whatever you want to call them, there seems to be a new trend in baseball to hire “experienced” Managers to run young ballclubs.

The Marlins have hired 80 year-old Jack McKeon and the Nationals have hired 68 year-old Davey Johnson.

So how long will these Managers “manage”?  How will they do with their respective teams?  And what does this new trend all mean for the game of “baseball”?
