What role, if any, does luck play in baseball? If it plays a role, in what ways and how does it effect outcomes?
On the one hand luck is nearly unmeasurable and certinally unable to be predicted in any fashion. On the other hand, we can all recoginize when a team's luck is "going their way" (geting all the calls, hits are falling, strikes are being called, etc) so there is some level of tangibility and value to it.
You can't build a mediocre team and expect luck to carry you to victory yet all good teams on paper hope for good luck to come their way and help them obtain the brass ring.
I'm guessing that views on "luck" will run the spectrum from irrlevant to essential.
Luck plays a role in every aspect of baseball from scouting, to player/trade availablity, to hitting, pitching, catching and running to schedule construction.
So I'm leaving the question very broad and open ended.
