If people need an exhibit to toss in muh face to show just how much coaching matters, exhibit A is Ted Cottrell and Norv Turner. These two have destroyed the identity of the Chargers, and have not attempted to give them a new one. Their confidence is shot, in themselves, and the coaching staff. THAT is what a bad coaching staff can do to a team, or look to the Raiders last year. In game, their plan might be pretty good - but the players can't carry it out, or don't feel like it.
Trolling some Bolts sites, it's hilarious to see all the "What are Phillips/Merriman doing out in coverage all the time" threads that we were bombarded with about Ware last year.
