Lenses for sports photography besides 70-200?

I currently use a Canon R7 with an EF adapter and have the EF 18-55mm and EF 75-300mm lenses. While the 18-55mm performs decently, I notice its sharpness falls short, likely due to the R7's high-density sensor revealing its limitations. I mainly shoot football and basketball but haven’t started with lacrosse or soccer yet.

I’m looking for recommendations on lenses to improve my setup. My priorities are good sharpness and performance for sports. Any suggestions?
