Were mistakes made? Yes, but what organization in the NFL hasn't made them at one time or another. I'm not sure Gurley applies to the term mismanagement. I think that labeling falls under the heading of hindsight, not foresight. Where they went wrong was believing the player when he says he's fine. Maybe they insist upon a medical physical before entering into a mega-contract. But then injuries happen on the field during games.
The question in my mind is how management responds to problems. I have watched their moves and overall I think this team is better managed than most. Bad management? Just look at the Chargers, Dolphins, and Browns. They made the right move with Goff because when you look at the escalation of QB contracts, his contract is pretty much in line with his level of play. He's actually 6th on the list when you look at his contract. Also, after this coming season, his cap hit drops and continues to drop until it's $26M in 2024. They front-loaded his contract to take the hit now with an eye on the other talent they will need to pay. That is very good cap management. So to fault management for an undisclosed injury really isn't right.
This FO has built a legitimate Super Bowl contending roster. It remains one of the most talented rosters with fewer holes and than most. Sure they lost Fowler but they have Ebukam and Floyd ready to take his place. They lost Littleton but in reality, Corey was too limited in this scheme and they gained speed at LB. They added Robinson to create a roadblock in the middle.
I say people need to quit looking at who is leaving and not who they have and where they are going.
They can grab a RB in the second or 3rd round if they feel so inclined. There definitely will be good talent at that position. In fact, the way Snead operates the only way he releases Gurley is because he's got his eye on a replacement. IMO he's looking at a RB in the draft. It's the one position that rookies normally can play well as rookies. Look at Gurley, over 1,100 yds, 10 TDs with a 4.8 yd per carry average.
Good management doesn't make a move without a plan. In every move, the FO has made the last few years it's been obvious Snead was working off a plan. I think he still is.
