Of course it isn't. But looking at the situation, does it warrant blowing the entire team to bits and starting over? The article argues that PIT missed 3 or 5 and didn't take the scorched earth approach to the situation. Not sure what you're advocating to fix this, but if it involves the dismissal of the HC, what was also pointed out in this article is that PIT is in because they have drafted top notch playmakers over the past few years and we have not.
The HC cannot be w/o fault. He has decision making capabilities as to who stays and who goes when it comes to roster cuts. Even if the players are not quite pro bowl players. And he has decided to cut players that deserved to stay to keep or bring in players like Hester which will forever be one of the worst calls he's ever made. He's made so many in game clock management blunders that have cost us at least 3 games this season alone. He has made poor decisions with coordinator hires that has left us with a 9 yr QB who is heavily reliant on a coordinator to help him play well. Our nasty streak has left the building and its what has kept us a dominant organization for years even with years of having an inept offense. This is Harbaugh's team now and I barely recognize it. I'm not saying dismantle or blow up the team, but staying the exact same would constitute insanity. Something has to change, and if keeping HB is what's done, then the coordinators and assistant coaches needs to be revamped, along with the scouting department.
Show your source that Harbaugh brought in Hester. You have no clue on how this front office works. The HC doesn't bring in players or trade players. More than likely, Harbaugh said to DeCosta or Ozzie, "we need a kick returner, what we have isn't working". Ozzie then goes to Moriarty and says, "we need a kick returner, what's the salary cap number we can afford". Ozzie then goes to Vincent (Director of Pro Personnel)., "We need a kick returner and we have $2 million to spend, who's available?" Jacoby Jones, Devin Hester, Player X, Player Y. Ok, call Hester, X & Y's agents and get them in here for a workout immediately - our 1st game is in 8 days. Player X said he has another workout with the Lions and will probably sign. Hester will be here tonight. Player Y can be here on Wednesday.
