I will start:
1) Giving Kyle Boller too many years. You either have it or you don't. We really wasted some unbelievable defensive talent. A serviceable QB probably would have gotten the Ravens one more Superbowl trip.
2) Giving Cam Cameron too long of a leash and tenure. This man cost us BIG time with his ways.
3) Not letting Flacco grow early and make mistakes so he could organically grow to perfect his craft and test his limitations; evolve into a tactician, help make the offense unstoppable. He would have evolved to become the leader early on. No question. Flacco is very good to elite, but how many of you think he still has a higher level that he should and would be at right now???
4) Not fitting Boldin into his correct role somehow not finding a way to keep him. Watching Boldin do serious damage in SF really hurts to watch. **cry**
