I really did try. Every space SHOULD only have one possible correct answer, and if there’s more, please tell me. I might’ve missed another possible annswer.

Also, I couldn’t make the last and final square work, so the answer to that one is just Lebron James. Also, every player in the grid is fairly recent, because I’m not old enough to know past like 2021 ish. Have fun! Don’t burn yourself out with this! You can ask for hints if you really need them, but I believe in you wonderful people!
