I am pretty old school and always coached kid to act like you been there before. A few high fives and a couple of "Yea's" then go get ready to do it again. I also remember all the comments when the NFL was called the "No Fun League" in the days even a high five might draw some yellow laundry. Truth is, if I played today I would be the same old school I always was, but I get that isnt' the game today. And, I admit, a few celebrations have been funny and I do want to see my team having fun. My biggest issue is when you do **** like that when you are losing. You losing, you got work to do. Shut up and ball.
For anyone who thinks the planning of these things happens during practice or film time...there isn't a coach in the league that would let that happen on practice time especially these days where time is limited by the labor agreement. If they want to plan and choreograph celebrations on their own time. Well, I reckon that is better than driving down McKnight at over 100, tossing furniture out of windows, fights outside of strip clubs, etc. etc.
In the end, I think the choreographed celebrations are mostly stupid, but what do I care as long as you are winning.
