I have a problem with that. It is a clear attempt to subvert rules. It should be illegal.
Confusing Dallas, assuming its something not too unsportsman-like is not subverting the rules.
Attacking the refs and trying to confuse them to get a clear advantage is definitely unsportsman-like and reeks.
The major problem with attacking the refs in this situation, assuming that was part of Dan's plan, is that this trickery in this situation is a guaranteed TD and in last weeks case would have been a guaranteed TD and a WIN.
The problem with competition, any competition, is that getting an advantage starts leading into things that arent about the sport...but about using your head to trick others. I dont think there is a way to keep a competition strictly about the sport at hand....there is always going to be someone using unsportsman like slight of hand or trickery to win...even if what won them the competition has nothing to do with the sport. Example...rumors about teams sending people in to the opponents hotel looking for playbook material that might have been accidently left behind. Going to that extent to win has nothing to do with two sets of players competing against each other....that has everything to do with off the football field antics to get a win or advantage.
How do you contain it?
At the end of the day it starts getting corny how far some will take winning. Its funny how there seems to be a large portion of people that think Draymond's antics are ok on a basketball court. Everyone is trying to play basketball while he thinks he's in a last man standing MMA match...but he's considered a winner because he went the extra mile into violence? I guess the same posters want to see someone who thinks he is in a strictly boxing match get his ear bit off too. People take it too far.
