Different plans have got to be made for that to happen.You can't go to the well but so many times and then you have to take a different approach to attacking the same defensive coverages.
I agree completely. From what I've seen, there is no speed at WR. With poor pass blocking there's just no way to make the passing game work with multiple WR sets.
It really isn't complicated though, the Cardinals have to make defenses respect the running game. Every defense is playing with their safeties way back so even if there was time to throw something deep there really isn't anywhere to go with the ball.
Generally though, a cover 2 can be attacked up the middle but without any speed at WR defenses are just clogging the middle in pass coverage. If the Cardinals had some speed they might still be able to beat this type of defense but Boldin is always hurt and was never fast to begin with, Breaston's knee must still be a problem, Urban can't catch and Fitz is getting double covered every play.
I don't know why they went away from the 2 TE sets that they were using vs. NYG. That seems to be the way to go and they were still running the ball well vs. Carolina so I really don't see what the problem is. They are going to have to over-run the ball at this point. This vaunted WR corps is not up to carrying the offense right now. Too many drops, not enough speed, not enough time.
EDIT: I wanted to check the splits and my assumption seems to be correct. Although the number of attempts is far different, look at the difference in efficiency:
2+ TE sets:
23/28 174 2TD
0INT 116.4rating
0 sacks
4+ WR sets:
117/189 1,325 5TD
8INT 74.1rating
11 sacks
Man, looking at the splits is pretty revealing.
212 of his 283 attempts(75%) have been at or behind the line of scrimmage or 1-10 yards.
by comparison, Peyton(56%), Brady(53%), Brees(51%), Rodgers(52%), etc.
He has 15 passes overthrown and 1 pass underthrown.
