No. Its the quarterbacks.
The pass protection has been good this year, and the receiving group is passable. There is no excuse for them to drop back there and stand around as if they don't even know the playcall, because they "can't find anybody." Time and time again they sit in the pocket until they either take a sack, or check to Lynch/Jackson. I've had it with the ineptitude at the QB position.
Chris Brown made a post in his blog about one of these losses (if memory serves, it was an Edwards game, possibly the MNF) that recievers were open all game long, and the ball simply never found them. We've seen people say that as the season went on, Edwards stopped anticipating that recievers would get open, and trust the system and his WRs...and instead would wait until guys were wide open to let it fly. And even of the recievers who were wide open...he failed to see far too many of them.
The running game is not that bad...15th in ypg (113.9), and tied for 13th in ypc (4.2). You can't pin this on the linemen. Its specifically the quarterback position that has held the offense back, imo.
Losman has always recieved a lot of criticism for holding the ball too long, with good reason. But he doesn't hold onto the ball just because he likes doing it. He holds onto the ball because he just does not know where to go with it, because he can't find secondary recievers and he can't read defenses. Thats why he hardly ever takes a three step drop, steps up and wings it...instead, we get pat-pat-sack, or pat-pat-checkdown. He hesitates because he doesn't know what to do.
For too many games, we saw Edwards put that same defficiency on display. The ball wouldn't come out on time with the play, and when it did finally come out, it was to his security blanket.
People will say "I don't know if I'm ready to give up on him"...but are you really ready to just hand this guy the starting job next year? This is the most critical position in sports. We need to bring in somebody who has a clue.
