Was the key to Gibbs' success his unique offensive system?

[GTripp0012]

I came upon a theroy tonight. Joe Gibbs probably isn't a special motivator. He isn't a wonderful clock manager. But despite his shortcomings, he was always competitive in defeat, and more often than not, victorious. Enter this season, where for the first time in a long time, Gibbs' team has been getting beat badly on the road more than once or twice. With the offense vastly outplaying the defense this year, it doesn't seem right to say that our offensive system is the cause for our struggles. It isn't. But now that we are not using Joe Gibbs' unique offensive system, maybe all he is to this team is an average coach. In the past, including 2005, we used his system that he created, and he became a folk legend. He certainly isn't doing a bad job right now, but he's just not good enough to overcome the talent discrepency we face.

Thoughts?
