The fact that your players are working up the anger in response to meaningless crap goes to show they know they're going to need something extra to hang with the Chargers.
You can take comfort in that can you, that although you will be beaten, the other team had to get up extra in order to beat you?
Your team has more talent in many positions, it is true, but it is way too full of itself and WAY over-confident. Pride goeth before a fall, son, and while you may win or you may lose, you are tipping the scales toward losing every day.
Where what you call "meaningless crap" takes effect is in the fourth quarter, when everyone is tired, and onlyh the mentally tough can keep going at full capacity for a play, collapse, then get up for the next play. Think Kellen Winslow against the Dolphins so many years ago. When the game is close to ending, that's where that "meaningless crap" becomes important. Players use the disrespect and insults to dig deeper, and suffer rather than let the other guy off the hook.
You will see. Your team may still win, but it is becoming more and more likely it will be humbled. Hopefully they will learn from this for next year.
Deep down you know this. If you had faith in your team, you wouldn't be over here desparately trying to convince us of how wrong we are.
