I know what you are thinking: You are simply wondering why him?
If ESPN's report that Brian Daboll will be hired as Miami's new offensive coordinator (The Herald has not as of this writing been able to independently confirm this), then you're asking why coach Tony Sparano hired a coordinator whose team scored fewer points than the Dolphins broken offense in 2010.
The Dolphins also scored more points than Daboll's Browns in 2009.
I don't have an explanation for you at this time. I'm hoping to get an explanation at some point. It's a tough day for that as I'm flying back from Boston today so timing might be an issue.
In the meantime, I can tell you Daboll (35 years old) is younger than Dan Henning, whom he is replacing. And he is an enthusiastic sort as the video below shows.
Daboll's NFL experience is out of the Bill Belichick coaching tree. He was hired in 2000 by the Patriots as a defensive assistant. He became wide receivers coach in 2002. He left the Pats in 2006 to go with Eric Mangini to the Jets as their QB coach.
In 2009, Daboll again migrated with Mangini, this time to Cleveland where he served as offensive coordinator. Obviously, he was on the outs in Cleveland when Mangini was fired. And now he is apparently on the ins with the Dolphins.
