Yes, tendencies and signatures for players never match their IRL counterparts.So that's why I'm not seeing the hitches and animation slowdowns in that gameplay?
For example if you go onto Donovan Clingan's dribble sig. in the default roster (the original (not sure if 2k updated it)) you'll see that 2k gave him every unstoppable guard dribble, when in real life that is nowhere near the case.
Every attribute and tendency from guys like CelticLG (ATD) and Sheitan (CoY) hit their marks on players to the point you have to work to score on players and when you do you feel proud that you did so.
CoY:
You already posted the recent ATD videos, but here are some streams of the roster from other folks...
