Maybe I was imagining things, but I remember that it was once said that hitting a buzzerbeater or getting a double-double add just a tiny bit to experience gained from the match. If that's true, maybe we could indeed say there is a kind of "future boost", at least in terms of slightly bigger experience (which helps players to play better).
I can confirm reading this. Not sure where is it from, can't find it in the manual. But I certainly do remember that hitting buzzerbeaters give an experience boost (not sure about double-doubles tho, but I do remember they mentioned somewhere along the lines of players being involved in highlights or something, can't quite remember, but buzzerbeaters were the only example given I think. Maybe in one of those "Ask the BB" threads?)
