Remember when the Dolphins traded Jason Taylor to Washington?
The trade seemed inevitable when it happened due to Bill Parcells wanting the team to get younger, and Taylor, despite his age at the time, was the most tradable asset Miami had. It wouldn't occur until July of 2008, when Washington would give up a second-round pick in 2009 and a sixth-round pick in 2010 in exchange for Taylor.
We know how the story goes from there: Taylor had an injury-plagued season in Washington, Miami went 11-5 and won the AFC East in 2008, Washington cuts Taylor, Miami signs him and Pat White is drafted and flames out with the Dolphins.
See, with the 44th pick in the 2009 NFL draft, a pick that originally would've belonged to Washington, the Dolphins drafted Pat White. Why did they draft Pat White? To run the Wildcat.
I kid you not.
Did Miami need a quarterback at the time? Yes and no, depending on your philosophy. If you believe that a team should draft a quarterback every year until it finds "the one," then this pick shouldn't have bothered you too much when it happened.
The Dolphins didn't know what they had going forward. Yes, Chad Pennington was their starting quarterback and was coming off an 11-5 season, but we didn't know what he had with Chad Henne yet, so it made sense to bring in another arm.
Now here's where I say if you're going to do that, you don't use a gimmick as the basis to bring in said quarterback. What makes Colin Kaepernick work for the San Francisco 49ers is that he can do more than the read-option.
White really didn't have the pocket presence or accuracy to be any more than a Wildcat decoy, and after a devastating injury the last week of the 2009 season, he would leave Miami on a journey that would include attempting to play baseball, suing the NFL, then dropping said lawsuit to come back to the NFL to play for the Washington Redskins in 2013 before being released.
As for what Miami could've (and should've) done differently with that pick? Well, Miami needed a center but had decided to fill that need with free-agent center Jake Grove during the offseason.
Yes, hindsight is 20/20, but the Dolphins could've waited until the draft and filled that hole cheaply by going after Max Unger from Oregon. They could've also addressed guard by drafting Andy Levitre from Oregon State.
