I noticed a lot of people using their arms a lot more than I usually notice. Players, on both teams, were putting their arms up and using them to jokcey for space with every challenge, whether the ball was in the air or on the ground, and surprisingly the ref let it mostly go.
i was watching this on the stream and their lad got past dunk so he just pushed him over, it was quite funny, however IMHO a clear cut yellow - he has to be careful!
