As usual, I agree with your assessment. X's & O's create greater separation than talent alone, IMO. Coaching staffs that can do both well are at the top of the heap. But, if you can put together a great game plan and are tactically adept as well, you can often win with lesser talent. What did Bum Phillips say....something about "he can take his'n and beat your'n, then turn around and take your'n and beat his'n".
Last year we didn't see much risk taking on defense. I hope that was more to do with employing a new scheme and a lack of trust on the back end. I hope Coach Willis will be more aggressive this year, or maybe it would be more correct to say, I hope Hud lets Coach Willis be more aggressive. Offense will take their shots as usual and we will definitely see more of Elijah getting the ball in space than last year. I'm anxious to see him taking snaps as well, though I think he would be more effective throwing the ball on play action plays, where the D has to think about defending the run first. We should be able to attack defenses in multiple ways, so whatever they "give us" we have the talent to make them pay.
