I very much agree. As I see it, the absolute worst thing that could happen is they bring someone in that blows up the entire roster just for the sake of making moves. This team has alot more talent than most give them credit for. IMO:
First and foremost, bring in a new coaching staff that knows how to properly develop and implement game plans especially for teams within our division, that knows how to motivate players, and that knows how toughen up the players.
BTW, a new GM and scouting statff should be givens.
Second, find a damn QB! We're currently don't have anyone at the single most important position in the game.
Otherwise, we have decent talent all over the roster; if they can stay healthy. Yes, Oline help is needed - but we don't need 5 new guys. Yes, we need help on the Dline, but we don't need 4 new guys. Yes, we need help at LB, but we don't need 3 new ones.
So, shore up the line with a top LT pick. Bring in a solid LB either through FA or draft. And shore up the DLine. Do that, with a good coaching staff, and this team is much improved and competing within the division.
