I wouldn't get into the deeper issues you're talking about and I'd just get into what Staple's job is.
A beat writer cultivates sources, collects information, verifies it, reports it to you.
A columnist offers opinion, a beat writer does not.
What you're describing, about the "why we had the fewest scouts", is really more investigative work and falls into the realm of the "sidebar" or the "magazine-style" piece. It is, in my view, a different animal than beat work. I consider it to be a good thing that Staple has managed to resist the temptations to let opinion creep into his work, which has been a disturbing trend in reporting since the beginning of the 24-hour TV news era. I would add that I think MSNBC, Fox News, and various other television outlets are just not doing what they should be doing; in my view. Cover the material, keep yourself out of it. What YOU, the reporter, think about the story is largely unimportant and is just self-aggrandizing. The story is the story.
Staple does what he is supposed to do, report the data he gathers. I think we should appreciate him for doing that and not criticize him for not doing a different job.
I'll give another example since I'm on a roll here. Dan Friedman, of the Blog Box, is a columnist. He writes opinion pieces and he does very little reporting. In my view, that is far less valuable than beat writing; which requires cultivating relationships and breaking stories.
Full disclosure, I have my bachelors in Journalism and before I was a lawyer (many years ago) I was a sports writer (college and high schools) at a substantially-sized circulation daily.
