I would argue that this has mostly yet to show up on the offense, period, and that it is pretty much mostly in the DBs at this point.
We have had our struggles at LB so much that we just replaced one or two of them with DBs. That's also a sign of our DB development though. DL has been solid - but nothing spectacular yet, outside of Suh. Promising, though not as extraordinary a story as the DBs have been.
On offense, we really don't have much. A couple of good prospects have played solidly, and Taylor's been a surprise with how we fit the offense around his electric running. But OL, WR, even RB: we're not seeing that same storyline as we are in the secondary. We have Rex, who was a solid 4-star, but D-tray has been underwhelming. At WR, it seems any outstanding athlete goes there to languish in obscurity (and this has been true for QUITE some time, extending beyond the current staff). OL never should have stunk to begin with, and we've yet to see a lot of real success with new guys, even in Year 3. But it is building in that direction, hopefully, now that Barney is cleaning up his act.
So really, I think it's the secondary, which is VERY promising considering how many seniors we lose this year. I'm excited to be able to reload there, because we've depended a lot on them and will continue to.
