"Connection or coincidence?

While perusing Twitter on this Fourth of July, we came across a blog post (thanks Eagles Insider) from Iggles Blitz, which could shed some light on the Birds' new defensive scheme.

One of the criticisms of Sean McDermott's defense was its complexity. His replacement, Juan Castillo, is expected to simplify the scheme.

"We're here to teach," head coach Andy Reid said in February after promoting Castillo. "We're here to take complex things and make it simple so guys can play fast. You won't find a better teacher than Juan."

Or maybe Juan's son.

Castillo's son Greg is a cornerback for the Iowa Hawkeyes, whose defense has been coordinated by Norm Parker since 1999. Parker runs a simple scheme – as described by bigtennation.org."
