Also expanding upon that point I did a lookup of missed tackles among linebackers and found this article by PFF which ranked tackling efficiency in a 3 year window. Some of those guys aren't playing anymore lol but it's fairly recent. I went and calculated average weight of the top 15 and bottom 15 in tackling and the top 15 weighed in at 247.4 lbs, while the bottom 15 weighed in on average at 240.7 lbs.
Based on what I've seen from this defense, the biggest reason for poor tackling is for the most part twofold. 1) Our line is letting guys get to the secondary level way too often, and when that happens of course there's going to be more missed tackles. Corners and even Safeties aren't very well suited to taking down plodding running backs alone in general. 2) Our linebackers are coming off major injury in addition to being undersized. Davis is the only one that reaches 240. The solution to this is pretty simple:
1. Upgrade the interior line. You do that by investing in DTs. I don't know about you, but there are some intriguing prospects in the draft and Alan Branch off the top of my head will be a free agent in 2013.
2. Get a little bit bigger at linebacker. The good news is Luke is still young so with an entire offseason of NFL weight training he should have no problem walking in next September at 245. He definitely has the frame to get that heavy, maybe even 250 without sacrificing speed. Other than that since we're locked into all these contract extensions it's going to be tough to get bigger there. Davis has kinda maxed out his 240 lb frame and at 237 Beason's approaching his max. I don't know how well they'll play at like 245 for example.
don't think there's much we can do about getting bigger LBs. i don't think aside from keek that any of them will get bigger. i think that they are good, strong, and quick enough...but just on the small side of things. something that has been typical of NFCS LBs for quite some time.
what we'd have to do is compensate. make sure the Dline is beefed up and that we get guys with good size at safety. there's been some debate in the draft forum about whether it's important to use size as a deciding factor when looking at safeties. i think we're in a situation where the safety(s) that we add have to be big (for safeties) athletic guys who can tackle.
i think we have good size at DE as well as good speed. i'd like to add another pass rusher...even a pass rush specialist like bruce irvin. DT is the big thing, though. i agree that the guys we have are band aids. i really don't like the idea of taking a risk on drafting one, though. too high a chance of busting and it takes too long to develop and that Dline really needs anchored now in the middle. picking up vets to fix the interior was the right move. we just need to find one or two better ones.
