I agree the defense is still very bad. The way the cowboys walked down the field at will the entire first half and scored 7 every time they got the ball, as well as the fact that Romo had more TD passes in the first half than incompletions says that in spades.
But how in the world can you think the offense is anything close to acceptable? They have 1 play maker, Fred Jackson, and he won't be around for too many more years. And one is no where near "enough". The Bills have one game, the short pass game along with Jackson running. Period. Disrupt that, as the Jets and Cowboys showed, and the offense is done.
Yes the defense is not talented, but neither is the offense. A few more good drafts, at the very least, are needed.
