First and foremost, thank you for taking the time to critically review the images and share your thoughts. I find them to be incredibly helpful.
1) My camera setting for this shoot were: RAW, Manual mode, Auto ISO set to max at 8k, f/2.8 (98%), SS some 1/200, 1/2500, 1/3200.
The impact of the processing times were far beyond simply waiting for the NR process to complete.The long time frame drove me crazy but more important, it prevented me from running multiple tests on a few images to determine what the BEST NR setting would be for these images. I still should have but was overwhelmed by the time issue. I personally agree that some of the images have a "plastic" look to them. With the new computer, I will select a couple of images and run denoise at a variety of settings to determine what I can achieve and the best settings for that outcome. In this case, I guessed at a setting and simply accepted the results.
I agree with your suggestion to drop the ISO. Since I am going to test several descrete ISO values I will likely not use autoISO and simply set the ISO value I want to use. First I will cut the ISO in half (8k to 4k) and adjust SS to achieve proper in camera exposure. Next I will cut ISO in half again (4k to 2k) and keep SS high enough to stop motion, which will result in an underexpose to the camera image (I will accept up to 3 stops under). By doing so I hope to reduce the analog to digital noise introduced by higher sensor senitivity and reduce the over all highlights from the field lighting. If I understand the concept of ISO Invariance this will dramatically reduce the in camera noise. Since the noise is lower in the base data it will easier to work with in DN and thus can't be increased by increasing the exposure by 3 stops in LR. The net result (I hope) is less noise and I will also reduce the "highlights" which will result in fewer highlight blowouts (helmet, face mask, reflective gloves, background lighting, white lines on field, etc) and will reduce the steps in my WF. Hope this makes sense!
After I run tests on the DN settings, I will likely run some of these photos at the optimized DN values and reprocess. I will post when complete and we can see what impact it has.

You're on the right track regarding experimentation and trying different 'recipes' to get the most from your camera while support your visions and craft. A few things I'm sure you're juggling with, but will throw them out in case:
- Got to stop the action. You can always do something about the noise in post..albeit it may look rough, but you can't fix motion blur unless that's an effect you're trying to add. Once the sun sets, lights blend with ambient light, and everything 'balanced'...I set f2.8, 1/1000, and manually adjust ISO based on location. Usually I can keep 6400 in the middle and bump it to 8k or higher in the end zones. Of course every place is different. You're on the right track to test and fine-tune your exposure recipe. So you know - the lowest I'd consider on SS is 1/800 and most shots in a sequence will show some bur, but may luck out where a couple are usable,
- As for handling noise, I'm actually experminting with LR Denoise to determine the best level per the ISO. So - I'm a work in progress as well and will be reaching out to the community for feedback and suggestions as well.
Look forward to hearing some updates on how your new computer and exposure experimentation goes!
