Just to show how powerful it can be not to zoom too much, I am going to let you in on a secret of one of my own pictures and ontop of that, one of the best pictures I have yet shot (in my own opinion).
Here is what I show people:
And here is the unedited original:
As you can see, the original gives me alot of options when it comes to cropping. Especially when it is for internet use. Not as much when it comes to bigger prints though.
I just try to keep as much data as possible intact before I start the postprocessing. The finished picture is often far from what I shoot. Ofcourse, when I can and got time to setup a proper shot, I do everything I can to get the original as close to the outcome I want. But at live events thats hard to do, and then I try to get more surroundings and such so that I get more to work with.
