i feel if the celebration is not overboard i don't see anything wrong with it. Usually you see teams cooling down during this time too-just a light jog and recognize fans. The coach should have control of the situation and show respect to the other team. I have had more teams trash talk on the field when we have been losing 5-0 or more...and i think that is more disrespectful than anything...knowing our team has no chance to win.
