I think that if there is general statement that can be made about the job Fisher and his staff have done with THIS team, for me, it's that they seemed to coddle the young players to a fault.
I know that many in here don't want to hear about them being "the youngest team in the league" anymore, and seem to view that as just another excuse. But its real, when you have THIS MANY 1st and 2nd year players being counted on to contribute in the positions they are in. The toughest thing for a coaching staff to evaluate, is how much you can throw at young players, before they are overwhelmed with information overload.
Fisher has been quoted too many times to count, when talking about Ogletree's progress. All throughout training camp, preseason, and into the season, he repeatedly would say, "he is seeing things for the first time." "As he gets more comfortable he will be able to react without thinking".
Now apply that same premise to guys such as McDonald, McLeod, who are now thrust into a prominent starting role. Include the same thing on the offensive side of the ball, with a WR corp who are ALL still in that developmental mode. RB's who are ALL in their 1st or 2nd year, who were in a limited role last year at best.
Everyone on the outside, tends to look at these guys and ask why is Jenkins, Johnson, Givens etc regressing? I see it more being a case of the coaching staff dialing it back across the board, as a by product of the aforementioned newcomers not being at a point where they can handle more. Regardless how "talented" these young players may be, they just don't have the same learning curve. Assessing which of them can handle a bigger load, and who cannot, is the biggest challenge for a coaching staff. It can also hamstring what you can do as a unit when you have no other option.
Then, they get to the point where they can begin to take the kid gloves off, and low and behold, they lose their starting QB. Like it or not, that has to change to approach the coaching staff takes when implementing game plans. Clemens cannot be expected to perform at the same level as Bradford. He has a totally different skillset.
This organization made the decision to move forward with this rebuild by committing to the young players. They have added a mix of FA's but as an overall philosophy, its the youth movement that they will live or die with. The plan is obviously to have a corp group of young player develop together, and build a long term solution, rather than a quick fix.
How it turns out, obviously is still TBD.
