I'll say this.... Under prior DC's, my frustration has always been the lack of effort that was shown on the field. We look lackadaisical at times. Under the new DC, people are flying around. At least, it looks like there is more effort.
Now... does that effort = results? Apparently, not yet. But, I think we will get there. The 3-4 requires some key parts. First, it requires a BIG space eating nose guard, as I call them. Someone that can fill the A and B gap, by just their presence. Next, 2 quick and hard hitting LBs. Yep, that would be Sam and Will.... Sam and Will have to be quick off that edge. The 2 Mike LBs just need to be able to cover that short route.
I think we have some of these tools, but not all of them. The secondary is young and we got shown that, last week.
This is a learning year. We will have some ups and downs.
