TV Sports Basketball
Timing shots and movement on court matters most
WWE 2K15
Reversal timing windows decide most exchanges
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.

Human opponents reward reading plays and fakes
WWE 2K15
Human opponents bait reversals and vary move timing
TV Sports Basketball leans a little harder on variance, though the gap is small.

Shot success has built-in randomness
WWE 2K15
Chain-wrestling rock-paper-scissors minigames add randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.

Substitutions and strategy management add a layer
WWE 2K15
Move sets, stamina and match pacing are learnable systems
