The only way you don't 'go backwards' is if all your best players come back. Martin retired - replaced, Tank gone - replaced, CBs injured - possible help there, LBs injured - sured up, got a RB that fits our scheme in Blue, and some big body DTs to help stop the run.
Everybody thinks Jones sucks as a GM but somehow falls into the 'show me the shiny object' mentality. Do more in FA, but don't trade for players unless they are cheap all-pro guys. Dak sucks but we need to get him more WRs so he can throw more. It's just weird.
Single biggest thing we can do for Dak is get the running game back in order. To do that you have to open up holes and Martin had declined a lot. I actually thought Hoffman was doing better. We upgraded there. We signed a few RBs in FA that we could, drafted a guy who will fit our scheme really well in Blue, and got another more prototypical back. Have to think our running game is going to be better, and by extension that will open things up in the passing game.
We kept Osa who should fit our DL scheme well, got another baller pass rusher and got guys to help stop the run and shore up LB and CB.
What else do you want?
