Allow me to please summarize the opposing opinion.
Yes, other teams have done this, players have come out and said so. NFL had to know.
Yes, the Saints were the only NFL team to be punished.
No, they were not "singled out" or "targeted"
Yes, they had stiff penalties levied, why? They were told to stop, and they refused to do so, lying in the process to the NFL.
Were other teams warned? Don't know. However, in all previous information from players, even retired players, it was player pools, not pools supplied and paid for by coaches. Also the $$ were no where near the amounts the Saints used.
Now, you will post again, that this is no evidence. Why? Cause you like to stick your head in the sand.
You can't prove anything on your end other than YOUR supposition. I at least can pull quotes from multiple players again including retired players that verify what we the opposition believe.
Net, you don't have a leg to stand on.
Thanks for playing.
