We don't have a clear picture on which positions will be premium, which middle of the road, and which scrubs. We don't know Rhule's/Fittere's blueprint, so we can't anticipate what we'll will do in the draft and FA.
I do know some thing about Fitterer and Rhule. They both love fast roster churning at the bottom. So our scrubs will likely be pushed hard to overachieve, and when they don't they be sent packing quickly for the next scrub. Churning the hell out of the bottom of the roster is way of trying to find overachieving gems asap. The drawback is that the burden is placed on the coaches to always be dealing with inexperienced new guys, and more so than the typical NFL team.
We also know that Rhule loves balance, so he wants to be able to run and pass very well. He places a premium on being able to run in cold weather late in the season and during playoffs.
In the past things were simple. We knew our scrub position on defense were the safeties. We had a system that didn't require the safeties to be high quality. Now we really don't know what is going on yet. The defense is still up in the air, so who knows what we're going to do in the future.
