Noticeable Difference with Koetter

Anyone notice how much faster the plays were coming in last night compared to previous years?  Our QBs had time to make adjustments at the line, audible, etc. with no real threat of delay of game penalties.  Last year, I swear the team was breaking the huddle with less than 10 seconds on the play clock on almost every play.  The only thing that can account for this difference is the play coming in from the sideline faster than it has in years past.  I thought that the play calling last night was very good.  I have wondered how much of an impact having a real OC would have this year, and so far, it seems like it might have a major impact.  Very glad that Koetter is here.
