Post hoc wishes mean nothing. I wish I had picked the right lotto numbers last week.
Are they *changing* anything about their draft procedures because of that "wish"?
A legitimate answer would be "no". Not every decision that turns out poorly in the rear view mirror was a bad one.
But we spent a first on a guy who wasn't exceptional physically, didn't produce that well, and had personality red flags, because he was physically the right size for something we wanted. Classic pick for "need" over *everything else*.
Meanwhile, we passed on a guy who would fulfill half that need and was otherwise a blue chip candidate.
I think the problem wasn't Marinelli, it was treating picks as a "it's your turn" basis for a coordinator, let alone a HC. Coaches generally come and go, and that's certainly true of coordinators. The front office needs a football vision for the team, and needs to hire coaches and sign picks accordingly.
Marinelli was a bad pick as DC. Worse to let him "buy his groceries". I think he was way too much identified with his Dline Whisperer reputation, and so too easily dismissed personality concerns on players.
That's fine to do for dumpster diving. Not fine for a 1st round pick of meh quality.
