Reasonable expectation, IF they are in shape and well conditioned. We haven't seen THAT in Dallas since Jimmy left.
Meanwhile we see it every year, teams WITH elite front 7s getting torched anyway, because of their suspect secondary.
To me it is a myth that a secondary is better because of a 'elite' front 7. It might LOOK better at times and overall statistically, but the meter is late in games where the suspect secondary gets torched anyway. They're not any better players, their abilities don't suddenly grow, their faults are masked, hidden for a time by the play of the front end. And even that isn't consistent, it's not a natural law. Plus you simply leave out the facts when the opposite is true - ever heard of coverage sacks? When the secondary simply gives the QB nowhere to put the ball, and he has to eat it.
You simply cannot get away with a bunch of slow dummies back in the secondary. A bunch of nit wits who can't even CATCH the picks that do get delivered to them. And who keep making all of the same mistakes because their idiot coaching teaches them to 'have a short memory' instead of fucking LEARNING from mistakes.
