The court of impatience within the Raider Nation has reached a verdict in the case of Oakland offensive coordinator Greg Knapp: Guilty.

Guilty of questionable play-calling, guilty of lack of imagination, guilty of killing the offense brought to life by Hue Jackson.

Though a few reached this decision after the first exhibition game, when the Raiders were shut out, some waited until the second quarter of the third exhibition game, when the Raiders failed to score in four attempts on first-down-and-close-enough-to-kiss-the-goal-line.

Others waited out the exhibition season, when teams tend not to reveal much, but joined in after the season opener, when the Raiders couldn't run the ball and failed to score a meaningful touchdown.

Nearly all Raiders fans, however, are smoldering beneath their loyalty, waiting to see what Knapp manufactures Sunday at Miami. Though it's too early to be a must-win game for Oakland, it's precisely the time for Knapp to present a reasonable defense of himself.

Meanwhile, Knapp is wondering how his "trial'' could end so quickly.

"It's (been) one game," said Knapp, fully aware of his fast-growing unpopularity. "Through my experiences in 10 years as a play-caller, I've learned which ones to stress about and which ones not to stress about. And this one ... we know there are some things we have to fix."

Patience is, in 2012, an outdated concept, banished by the digital age, which has produced Twitter and a million other forms of interactive, and often brutally reflexive, commentary.

Besides, it's hard to ask Raiders fans to be patient when they haven't experienced a winning season since 2002.

And it's particularly difficult to hear Knapp plead for patience after he inherited an offense that was the strength of a team that narrowly missed the playoffs last season. With quarterback Carson Palmer around for offseason workouts and a full training camp, it was anticipated this unit would be markedly improved.

Though four exhibition games and the season opener, though, the question is who killed Oakland's O?

Any defense of Knapp, including my own, consists of noting he has been working with some of the weakest wide receivers in the NFL, journeymen tight ends and an offensive line trying to learn his zone-blocking scheme.

Among the players on the field thus far, only running back Darren McFadden represents a real challenge for a defense. If he remains the only threat, Knapp has no chance. The Raiders have no chance.

Though first-year head coach Dennis Allen appears to be a terrific influence on the defense -- the unit finally is offering real resistance to opposing runners -- it will look as if he turned to the wrong offensive mind.

Knapp's trial is heating up. He needs help, needs witnesses, needs to prove he deserved another chance with the franchise that let him go after the 2008 season, following two futile years with JaMarcus Russell.

Denarius Moore, Oakland's best wideout, is expected to make his first appearance of the season. He should provide a measure of dimension, which would greatly aid an offense that last week had little more than McFadden.

"We're also getting a young player, Rod Streater, caught up to speed,'' Knapp said. "(Rookie wideout) Juron Criner was having a good camp until he got dinged. Getting these guys back and healthy will improve our chances of getting the ball downfield.''

These are Knapp's solutions? Maybe. But the O.C. is seeking an awful lot from young men with little or no history of success.

It is generally sound strategy that any individual on trial not testify on his own behalf. And, honestly, Knapp can say anything he wants because his words are not facing charges. His offense is, as it should be.

Knapp is firm in believing McFadden eventually will thrive in his blocking scheme, which is different from the power scheme preferred by Jackson, the dismissed former head coach under whom D-Mc flourished.

Knapp also implies a full roster will allow him to expand his play-calling.

"Patience," Knapp reiterates. "Hey, it's one game.

"I believe the team that won the Super Bowl last year was 9-7 And they had their struggles on offense at different points during the season. So it's going to take some patience. Players need to have it, coaches need to have it ... it's going to take some time.''

I'm skeptical that the Raiders are this season's New York Giants. Raiders fans doubt Knapp can operate a productive offense. Though some have made their decision, all must beware of rushing to judgment.

Evidence presented thus far, however, has not been in Knapp's favor.
