Bingo (Orlovsky)! If you wanted Trubisky to be instantly good you should've A) wanted him to be protected as best as possible, not just good enough and B) given him weapons that were expected to make a rookie QB better not weapons that can produce with a vet.
The idea of making a great defense the greatest defense was not about helping the QB, it was about helping the scoreboard with a young QB playing like a young QB.
Most of the stupid fans complaining about the young QB are the exact ones who wanted everything that causes this kind of growth from that QB. Although the GM and HC are who is to blame, the fans wanted exactly what they're getting.
They will claim they wanted a HOF QB in his 2nd year that would make all those questionable offensive players better but that's not realistic. Gee, I didn't want to stab my finger, I just wanted to poke the knife between them faster than the other guy. No, you did something stupid with predictable results, you are responsible for the results.
