My issue is just how weak our depth seems to be at every position on defense except safety and defensive line. Cornerback is stacked with fancy names, but I remain unconvinced that they will develop into a force this year. Preseason was not a pretty time for that group. OLB still concerns me, even though one of our current top 3 defensive talents plays there (Perry, not Matthews). I'll admit that with the adjustment to assignments that Elephant has introduced the last few years and Nitro is introducing now, this same personnel group could go from worrisome in a traditional 3-4 to exceptional in a modern 3-4 (with the hybridization of DE/OLB to EDGE and S/ILB mixing), but until I am shown that I will remain pragmatic. I know that I have a reputation for pessimism here right now, but with what we have it really is more pragmatism than pessimism. I actually am optimistic that this new organization and assignment scheme could pay dividends, and in that context the addition of Brooks and Dial are coups, but if we keep playing the same old 3-4 those two guys aren't enough to address our issues.
And still, even if we do fully modernize our 3-4 and it works out perfectly and we don't have injuries, our CB corps has a LOT of stepping up to do.
