I wanted them to go after Cooper, but he wasn't playing very well, and trading away what is becoming a pretty high 1st pick could have blown up in their face.
I'm not going to wring my hands over what they will do in the draft right now. I expect them to upgrade with a couple new starters on the O-line (say, a FA and a high pick), add another receiver (either a big name FA/trade, or a 1st pick), draft a RB in the 2nd or 3rd round, and try to get a decent TE somehow (most likely. an older FA). That would be my mindset going into the off-season, and I assume they have a similar outlook.
Upgrading 5 positions on this offense would be a pretty big boost.
