The coaches are not the problem; sure, the play calls can improve. But I believe these guys can do it.
The players are not the problem; the elements are there, minus a couple positions. Overall, we're fairly deep though.
The answer is the SYSTEM we're in (and I'm talking defense here). This offense can make plays, and if we can get the run going in the final games and into next year, I'm fine with it. BUT WHY DID WE GO 3-4?! When your 2 best players on the defensive side of the ball are defensive ends who put up great numbers in '06, why would you move one to linebacker and not only hurt their individual numbers, but the chemistry and make-up the entire defense to begin with? We have no pressure because the opponents don't have to worry about the ends- hell they only have to worry about 3 players period. We have linebackers who are great for a 4-3, but when it comes to coverage, it's not their specialty. Then there's the secondary- most importantly people like Watts, who in a 4-3 just had to worry about that 1 guy running deep. However in this Tibesar design, he's got to cover deep and everything the LB's can't pick up.
Flat out, I said it early in the season, you need ATHLETES to run a 3-4. Freakishly big and fast athletes. We have the perfect players for a great 4-3....so can we go back please while we still have some guys to do it?
