This is the EXACT thoughts I was having before I went to NFL.com and saw this article.......
"Matt Cassel is struggling behind the Chiefs' leaky offensive line. The Chiefs' franchise quarterback has looked nothing like the efficient playmaker who guided Kansas City to a division title last season. He's completed only 12 of 27 passes for 182 yards in two preseason games, and failed to find a rhythm.
Part of his struggles can be attributed to the Chiefs' offensive line woes. The unit has failed to protect Cassel, whose accuracy has suffered amid constant harassment. Cassel completed only two passes to receivers in the loss to the Rams, resorting to a host of dump-off passes as defenders clamped down on deeper targets all night.
The offensive line's struggles have also limited the impact of the Chiefs' running game. Without a punishing ground attack to set up the timing of the play-action passing game, Cassel has been unable to push the ball downfield to Tony Moeaki and especially Dwayne Bowe. The duo made a living off deep throws executed off run-action last season, but those opportunities have been relatively nonexistent during the preseason."
