Hey... looks like you were having so much fun, I would just jump into the deep end with you all. We are completely ignoring metering method... except in the case of manual. If you use spot, or evaluative, center weighted, partial... etc. What is nice about the newer cameras is if you shoot spot, it will spot meter the same area that the focus point is selected.
Exposure varies widely in field sports... except from 11 to until about 1. Outside of that you will see wider ranges of exposure depending the time of day and position of sun. You can go from complete shade to full sun in one panning motion following a play.
If I am in an auto exposure mode, I always use spot. Uniforms, angle to the sun, venue shading, are lights augmenting.... or whether it is cloudy, or clear skies... it all depends.
With new cameras and their improved dynamic range... you really have so much more latitude and can correct easily 1 stop of difference within the image.
For me, I am usually shooting wide open of f2.8...I still set max ISO to 6,000 for most sports... stuff like indoor track is at 12,800... and let the shutter be what it will be. I know others like to lock in a shutter speed and go with variable ISO.
No right or wrong... but for me... spot or zone metering.
