OK, you're pissed because they let Sherman go.
There's a time when every player will be let go if they don't go on their own accord and with Sherman's injury, his salary, and the Cap in it's then situation something had to be done and the risk/reward for keeping Sherman was too imbalanced to keep him on the roster. It's football and choices have to be made.
Regarding Pete, he's a Defensive coach and like Holmgren before him, he knows one side of the ball much better than the other. That's what's really going on here with the OL and Offense in general. Every coach has their flaws. Some can still win with them and others can't. It was time with this team to tear down the Defense and start anew. Today's Salary Cap rules demanded that big changes be made, and they are doing just that.
It's difficult to lose players who got us to the top of the mountain, and most of us will mourn their loss to some degree but now it the time to look forward to another fun time rebuilding a championship team.
