Need help deciding on a lens

[Lkcphotos31]

I am a sports photographer who currently shoots on a Eos R and an ef to rf adapter that connects to my ef 70-200 f/ 2.8 L IS USM, the first generation of 70-200. My current lens has a foggy not sharp look to it during low light so I am looking for a different lens, I cannot send it in for repair because it is too old and they don't service them anymore. I cannot decide between the rf 70-200 and the ef 70-200. If anyone has any advice let me know! I am also looking at a 24-105 f/4 for the upcoming basketball season so if anyone has strong feelings about this lens please share.

Lkcphotos31 the google drive works but I only see a jpg in the drive. Can you drop a couple of the RAW images full size on the drive. 

Also, the image that is loaded, it appears that you are shooting from a low angle up and there are stadium lights directly behind the shot. The camera appears to be fairly close to ground level. Is this an accurate assessment? The fogginess that you are talking about could be/appears to be flaring or bleeding from the stadium lights.

this should work let me know if not. Why does the flaring or bleeding from stadium lights not happen with my other lenses?

Not sure for a fact that is what it is but on that specific shot it looks like it to me. Just an observation that it may not be a equipment challenge and more of composition challenge.When you use the other lens are you shooting from a low position into the stadium lighting? There are variables I can't see with the other lenses you are using but the one example image it seems fairly apparent to me. I could be wrong.

If you look at the second image you posted, I added it below, it appears to be straight on shot with the stands in the background, camera shoulder high and level, no fogging or flare in the image.
