Here is he opening to my Wednesday column about Jim Harbaugh’s sideline behavior:

SANTA CLARA — Go on the internet. Look for a video called, “The Best Jim Harbaugh Freakouts.” It’s easy to find.

It shows the 49ers’ coach freaking out on the sideline during games, a wild man throwing his clipboard, screaming at the refs, screaming at who knows who. Just screaming.

If Harbaugh were a child, you’d call it pitching a fit. You’d send him to his room. This I freely admit, the freakout video is funny and there’s something elemental about Harbaugh, even enjoyable. But you probably wouldn’t invite him over for dinner. If he didn’t like pot roast, he might throw it or you out the window.
