Will 'Hard Knocks' affect Dolphins' record?

Chris from Chicago writes in our AFC East inbox:

Long-time Dolphins fan here. I'm thrilled to have an inside look at the franchise on “Hard Knocks.” But I'm not thrilled about what it may mean in the win/loss column, and how it effects the development of our end-all, be-all franchise QB [Ryan Tannehill]. Here's a blog idea: Can you take a look at the W/L records for teams when they were on the show? Of course, it won't predict their record, but I think it would be an interesting study.

Thanks for the note, Chris. After doing some research, it turns out the results are split pretty much down the middle.

Three of the six teams that did HBO's popular "Hard Knocks" series made the playoffs. Four of six teams have had winning records. The Dallas Cowboys were 9-7 in 2008 and missed the postseason by one game.

Here are the team-by-team results:

There are a couple things that are interesting to note. For starters, the overall record for teams on "Hard Knocks" so far is 49-47, just over .500. Second, Miami will try to become the third consecutive team to make the postseason after filming the show during training camp. The New York Jets (2010) and Cincinnati Bengals (2009) accomplished that feat in back-to-back years.

As far as Tannehill, I doubt the show affects his development all that much. Tannehill will be a storyline for HBO, but he won't factor much into the Dolphins' plans until late this season or 2013. The show should have more of an impact on the two veterans competing to start for Miami in Week 1: Matt Moore and David Garrard.
