Of course we as fans can't see the whole field, we don't know which defensive play are called or what each players assignment for every play is, but what I think most of us are complaining about is missed tackles and poor pursuit angles. Those type of mistakes can only be assessed to each individual player who makes them and not the entire defense. Yes, blown coverages are part of the problem too, but having a poor pass rush or a linebacker not in the right coverage doesn't cause our safeties to miss tackles and take the wrong angles of pursuit. Those type of mistakes are each individuals responsibility to correct and it was nice to read about them manning up to it in that article. Now they just need to work on fixing it.
I'm for one am tired of not seeing anybody wrap up on tackles. Instead we have guys diving in, head down, trying to punish a runner with their shoulder pads instead of sticking to the fundamentals of tackling; using an athletic body position, changing elevation, and wrapping up!! How hard is it?? We could seriously cut our yards given up by about 50 a game if we just made our tackles on first contact.
