Well, let's keep in perspective that we are implemented completely new systems on BOTH sides of the ball that are radically different that what we did before. So it isn't unrealistic to expect that it will take a few recruiting cycles to optimize our roster for what the new staff is trying to do. Or that the players that the new staff inherited aren't great system fits for the new schemes.
I get that people are frustrated, because the last 17 years have mostly been frustrating and disappointing. But we finally have a head coach and a staff who know what they're doing and have a track record of success. IF it takes them a little bit of time to get the roster where it needs to be, that will be the price of sustainable, long term success and worth the short term growing pains.
And along the way, we can still WIN games, even if the roster isn't optimized, as you point out. This isn't a full rebuild, and the offense can still win us a lot of games. But on the other side of the ball? That's where the majority of our personnel issues are this season, no matter how else people would like to spin it.
