Ok, just from what comes immediately to mind:
1. That Griffin lost his Job the moment Gruden was hired, unrelated to Kirk
2. That Mike Shanahan destroyed any hope that Griffin would have even modest success long term.
3. That Griffin wanted to become the type of QB with more than a fleeting stay in the NFL, and once he suggested publicly that's what he wanted, there was no stomach in the organization to sit him and properly transition him into the pro game. (BTW: that die was cast once he was named starter after being drafted)
4. Injuries
5. Me, me, me from Griffin
6. Snyder's favorite who gained veto power from an impetuous owner
7. Weak, professional football management group, who were paid to build a winning program but selected to keep their jobs instead of doing the correct thing despite the owner.
1) didnt gruden start him for a year ?
2) MS had no choice but to play him ,
3) RG3 wasnt ready to be that kind of qb and he failed again at his next stop
4) he was uninjured when KC took over
5) If me me me caused him to be benched because he wouldnt listen listen listen while the other guy did did did listen then he got beat out
6) that would work against KC beating him out
7) i dont see how that worked in KC's favor RG 3 was the anointed one
