This quote from Samuels says it all

[Stacks42]

Here is another telling quote:

Several veterans said they have learned to brace for confusion on the sideline in crucial situations, and doubt it will change nearly four years into the regime.

"It's frustrating, but it's not anything new to us," one said. "We look at it like it's something we have to overcome."

Another veteran said that players talk among themselves about the coaching decisions, but that he did not sense the players would begin turning on Gibbs, who has praised their effort each week. Tackle Chris Samuels, a Redskin since 2000, said the players have more than their own share of problems to overcome, rather than worrying about coaching decisions.

"I just take care of my business, I don't question what the coach calls," Samuels said. "He gets paid a lot of money to do his job."

from the post "gibbs defends his calls". You can respect the man (as I do) and still agree that he just doesnt have the killer instinct anymore
