Let's start on offense, where Dan Henning was non-committal late in the season when he met the media as to whether he wanted to return for another season.
Henning has repeated throughout the last two years that he was having a lot of fun with the Dolphins after coming out of retirement, but let's not forget the fact he's 67 years old and at some point he's going to decide he's worked long enough.
Head coach Tony Sparano didn't make any declarations regarding his assistants when he met with the media the day after the Pittsburgh game, but the feeling is he'd be happy to have Henning back in 2010.
The same might not hold true for defensive coordinator Paul Pasqualoni.
The Dolphins had a rough year on defense in 2009, and a source told Scout.com NFL reporter Adam Caplan that the Dolphins have been making calls to see which defensive coordinators might be available after the playoffs.
One guy who is available and has a history with Bill Parcells is former Browns head coach Romeo Crennel.
There's also been a lot of talk about the Dolphins bringing in former Jets head coach Al Groh, another Parcells disciple.
Regardless, that one bears watching.
