Absolutely. I think the players are behaving differently. My thought is that the games will appear to be more similar to training ground practices where the opposition are your own teammates, so the sorts of tackles and behaviour the players express will be different as you don't want to risk injuring your own teammates. Overall i think the quality of football played has improved without crowds although it's not the same experience without the fans.
