A very nice set of action shots, Paul! (as we frequently witness here on
the list)
Your comment about the way you cropped got me puzzled and intrigued,
so, I was curious what happens in your photos in that regard.
My procedure of leveling (for non-landscape-with-clear-horizon-at-infinity
photographs) is the opposite to what you've described:
Usually, for the photographs that don't have a clear horizon at
infinity, it is hard to figure out which line is truly horizontal:
Even a small panning away from the point where you are looking at exactly
the right (90 degree) angle at that horizontal feature would make that
line non-horizontal.
In contrast, the vertical lines remain vertical, unless you have a
perspective divergence/convergence (which is more prominent with
short-focal-length lenses).
The perspective divergence/convergence (depending on whether your viewing
point is below or above that vertical feature end-point) happens on the
sides, so, even in case of that effect present, I usually rely on the
vertical features in the middle of the photograph: fence poles, light
poles, vertical building edges, etc.
So, while it is not very distracting, a few shots (e.g. 8671 with the guy
panning, or 8710) have the vertical lines (vertical fence poles in the
background) all leaning to the same side (to the left), which is
non-physical.
I am not saying that all photos must be leveled, some photos a better
tilted. My comment is just on the procedure of what is the true
horizontal/vertical.
Cheers,
Igor
PS. Of course various types of distortion, e.g. barrel distortion, can
affect how straight the lines are. But then one has to deal with those. :)

A small gallery of pics shot under the lights at a school stadium. Good
illumination, but nowhere near daylight levels. To get F8 @ 1/640th I had
to hoot at about ISO 30,000. The verticals are all cropped from
horizontals. Most pics are cropped somewhat. I think they held up fairly
well in terms of noise. All with K-1 and D FA 150-450.
