I agree with everything you posted except the part about 8-4, 9-3 not being good enough. Look, the fact is, the team regressed this year. I've seen people boast that we won 3 more games, and that is proof of "improvement".
But if watch what happened ON THE FIELD, the results got progressively worse this year as things went on. In 07, it was bad all year, but by the end of the Stanford game, you thought, ok, things might be brighter in 08, they look better. This years team peaked, arguably, with the Purdue game, and things only got worse (except when Ty is on the other sideline, which is no coincidence). JC clearly regressed. The ground game never did anything. 6-6 just didn't look any better than 3-9.
The point is, the NUMBER of wins doesn't matter, its what the gameday product looks like. If we went 6-6 again, but were really competitive with everyone including USC, then I could live with that. I could also see skating by a bunch of junk teams with a 9 win season, and getting humiliated in a bowl we probably didn't earn by play as much as reputation (sound familiar?). That would NOT be improvement. The NUMBER of wins doesn't matter, but I must see improvement on the field.
