Agree on the hypocrisy of the ad thing. And it wasn't the wave. It was the slowing down while in play and looking back at the DB. The fact that Lamb could have been injured is why he shouldn't have done it in the first place. If Mills wanted to be a real jerk, Lamb could have been done for the season. And for what?
Where is your source for that? Every source I've seen stated that it was for the wave. And your defense of Mills is strange. Ceedee already scored and then the shove. If that isn't unsportsmanlike conduct as well, then what is? Should Lamb have slowed down? No. Should that give Mills a free pass to shove after the TD? No. Would Lamb have waved goodbye without the shove?
You also go on to defend Rodgers who used profanity to taunt fans. Taunting fans is not against the rules. However, his little champion ship belt moves against opposing players is and he still does it. Using profanity to taunt fans could also be considered conduct detrimental to the league.
Until the league is consistent in enforcement, there will always be cries of bias and rightfully so.
