The four games I played to experiment went like this:
1st game: I'm down by 11 points in the 1st q with the '04 Pistons against my friend who's the '08 Celtics, and I eventually tie the game at halftime and lose by 2.
2nd game: I'm playing a random online in MyTeam and I'm up by 12 at the half. Start of the 4th, I'm only leading by 2. I eventually win by 7.
3rd game: I'm winning again by 9 points start of the 4th against the CPU in a quick game on Superstar, the game is then tied with 2 minutes to go. I pull away and win by 5.
4th game: No major lead against this random online guy in quick match, it's just a close game through and through. Seemed like my guys would miss the easiest shots when I was up by any margin, same thing for him.
Definatley not happy about this being back again. I do think however, that the rubberband effect has been nerfed from 2k15 when it was blatantly obvious that it was in the game.
