There's nothing wrong with being spontaneous and celebrating when you are excited and make something happen on the field, but I agree that planning and choreographing is NOT SPONTANEOUS.
Considering how ridiculous some of these celebrations are, let's take it one step further. If I was coach of either Hamilton or Winnepg and caught wind of these guys placing more focus on the stupid celebration dance they are going to do when they make a play, I would have a hard time not sitting that player down to catch some splinters that week.
The teams that are doing well need to reign it in a little because it is no longer spontaneous and exciting, it is telegraphed and embarrassing. What would you have next? Perhaps the entire team should break into a "spontaneous touchdown dance". I'm sure the cheer team coaches would be happy to choreograph a routine or two for them to use. Seriously though, there are times when it borders on taunting and definitely times when it shows little or no class and just smacks of arrogance.
As far as teams that are not doing well, again, if your team is having a losing year and you are still worried about what stupid little dance you are going to use "if and when" you score, maybe you are in the wrong profession. Shouldn't you be worried about what you are going to do to get into the end zone and help your team instead of what you are going to do after? Add to that how stupid it looks coming from guys that are on a team that has only won one or two games. What are you celebrating, your first and only TD of the season? Maybe you should score a few more before you start dancing so it looks like, you know, you've been there before.
