So, if Curran is right, Lazar was wrong. And I think most of us, if not all, hope that Curran was right.
A lot of needed moves are pretty easy to see:
Patricia and Judge need to be shuffled to other spots. Judge to special teams and Patricia to a special assistant makes sense.
Bring back the old system and an O.C. who's run it (That means no Kingsbury!) and can get Jones back to a good place mentally
Get a left tackle (Brown can be shifted back to RT), a CB1, and a WR1
Get speed at ILB
Get a speedy FS if McCourty retires
There's plenty more, but those are nose-on-face level obvious.
