Positives - Darrisaw and O'Neil look like better than good tackles, Cleveland improved at LG. He misses some blocks but he's good and he's really good on double teams. I like Ingram and think he'll be better with a season under his belt. Since I was mostly worried about the O-line coming into this season, this was a nice surprise.
Jefferson + Hockenson + Osborn look like they'll be a solid core of receiving options going forward. (I think Theilen gets restructured). Reager didn't get a lot of looks but I wish they had given him more opportunities. They might have some solid depth without needing to add too much.
Negatives - the defense was horrible. The 3-4 scheme didn't work, the umbrella coverage allowed other teams to move at will, we were bad against the run. Kendricks, in particular, looked completely out of place in a 3-4. Hunter covered RBs on obvious passing downs instead of rushing. That's on the coaches. Scheme better.
I'd invest all the draft and FA capital into the defense. Looks like the draft has a number of good CB and a few DL that could fall to us at 23 but also some good depth behind that. Get a new defensive coordinator and strongly reconsider the 3-4 scheme. I think Hunter and Wonnom are better in 4-3 scheme as DEs. I think Smith can be an OLB in a 4-3. (admittedly, maybe I'm wrong). The secondary is a huge mess. Not sure what to do but try to upgrade everyone. (I assume Peterson is gone in FA and Smith retires). I don't think the defense can go from 31st to top 10 in a year but if we could get a solid line, make it harder to rush, and generate more pressure without blitzing as much, maybe it could protect a bad secondary? Make them a top 15-20 defense to go with a potential top 10 offense? That could be a fun team to watch.
