Let me make sure I understand this thinking correctly. First, Pendry was the OC at Carolina when Capers was the HC. Second, things were not going very well (similar to our current offensive situation?) so the owner forced Capers to fire Pendry. Third, Capers is fired at the end of that season by Carolina. Now, the thinking is that Pendry is going to replace Palmer. Deja Vu. This duo of Pendry and Capers didn't work before, so why would it now?
I've said it before and I'll say it again-Capers is the problem. He is a micro-manager, which means he wants his hands on everything. His coaches are on a very short leash with respect to their decision making. This is especially true with the OC. Palmer may call the plays but you can bet his selection is from a short list approved by Capers. Capers is not going to change because-first-he'd have to admit that he is a (big) part of the problem, and he doesn't believe that. Read his interviews--ever hear him accept blame?
IMO, as long as Capers is here, the problems will exist. He has built a system that-to succeed-relies on perfection from every player, which means one bad play destroys everything. That is what we are seeing on the field right now, a lot of 'little' failed executions that result in confusion/penalties/turn overs/wrong reads/wrong routes, etc. etc. What we need now more than anything is a system that is based on the K.I.S.S. (Keep It Simple Stupid)
method, where everyone is 'on the same page/knows their role' and work that role to perfection. Two examples of this are Pitts running attack that everyone knows is coming but they still work to perfection and succeed with and the pitch/sweep/run play that the Packers are known for. IMO, our system is so confusing/complicated that the players--more often than not--are placed in a no win situation. I hope I'm wrong-but as the Panthers found out-replacing the OC didn't work.
