OK lets look at what has happened here since Stoops arrived.  The first year Stoops inherited an absolute mess of a roster with just a handful of SEC level athletes to play with.  He did in a very short time period help that years recruiting immensely.  That year we were predictably terrible and it showed on the field with two wins.  
The next year we started out of the gate with a bang although it was a schedule front loaded with the easier games that year.  As we got into SEC play and a hard SEC grind at that, our very thin roster showed it was not up to SEC level and we did not win a game the second half of the season.  National writers for sports publications talked of a second half collapse paying little attention to the intensity of the schedule increasing four-fold the second half of the season.  Worst yet the few players that were here when Stoops got here and some outstanding JUCOS who were SEC players (Bud, Z, Miller, and Blue) graduated making for more roster challenges.  Even so we go from 2 wins to 5 wins,  good improvement but a feeling of let down because of the schedule being back loaded with SEC teams.
The third year we have to replace our OC.  The man hired was the third person Stoops wanted after Riley and Gran didn't take the job.  We play with a roster of mostly sophomores and freshmen and again start with a bang but finish poorly.  That year is worse than before because expectations have risen.  Although the roster has been improved a great deal, there is no team unity or chemistry and players start to go their separate ways it seems.  Whatever happened internally most people feel the main characters (coaches and players) in last season tragedy have for one reason or another left the team.  Again 5 wins and a second half of the season disaster.
Looking forward we can say that the roster although still younger than what one would want heading into a SEC schedule has been significantly upgraded.  A person could reasonably say our coaching staff looks to be upgraded as well.  Certainly our facilities are much better and continue to improve.  It is kind of hard to disregard all that has been done to improve our football team and facilities when judging the job Stoops has done.  I kind of wonder what Rich Brooks has to say when he comes back and sees what is being done.
When considering all that has been accomplished in just three years to improve our program I do think that merely looking at the wins and losses of our program does not tell the whole story.  We here have been ranting about how behind we are as a program and most, not all but most of our structural improvements are done or are in process of being completed.  It is only fair to look at the immensity of the job Stoops had waiting for him and all that has been accomplished structurally when judging the job Stoops has done.
It cannot be denied that we are in a much better position now with Stoops than we were when he took the job.  Plain and simple.
