We began our research by looking at the basics of run defense – including a successful demonstration by New England – before moving on to examples of failed execution in filling gaps and flowing to the play side. As we wrap up this series, we’ll see that proper interior filling and responsive flow aren’t always enough to get the job done – players must choose correctly among possible assignments, and failure to do so can lead to a running back breaking free.
In short: KEEP. RUN. CONTAIN. But please click and read, too.
