“Perhaps the Dolphins utilize three safeties and only one linebacker in sub packages – with Fitzpatrick, Reshad Jones, T.J. McDonald and the best coverage linebacker the Dolphins have at the time on the field all at once,” Salguero writes.
My own thoughts are along this line but are more conventional. What I envision the Dolphins doing is playing more of what is known as the “Big Nickel.” This is a standard nickel defense with an extra safety rather than an extra cornerback. The defense has become more and more popular as a base defense over the last few years.
