Football sim testing execution and opponent reading under a studied tactical meta.
ESPN NFL 2K5 leans Execution (Grand Arena); FIFA 21 leans Execution (Competitive PvP).

ESPN NFL 2K5
Stick skills on passes, jukes, and tackles
FIFA 21

Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
ESPN NFL 2K5
Play-calling is a guessing duel against humans

FIFA 21
