Higher standard

Vikings coach Brad Childress noted yesterday that a defense can get away with a mistake by a player more often than an offense. His point: the left cornerback can play the wrong coverage, but the offense runs the ball off right tackle, and the middle linebacker and right defensive end make a great play.
But the mistake of an offensive player is often more glaring.
"So yeah, you can have ten guys doing the right thing (on offense) and one guy that is a little bit off and the play looks like slop," Childress said. "It's just hitting all the keys on a piano. Everything sounding right, being right. That one little key that's not right makes the whole thing sound bad, in this case look bad. "
Childress is being patient with his offense. But he made a telling comment during his press conference Wednesday.
"First of all you don't question anybody's effort, but just to know exactly what standard of performance is going to be there from every guy, every time," Childress said. "At different times it's been a little bit uneven. You know it's going to be different for different people. That's the easiest way to say it."
Anyone want to venture a guess which players he might be talking about?
