The Eagles denied the Jets permission to interview their quarterbacks coach John DeFilippo for their offensive coordinator vacancy, a league source tells Adam Schefter of ESPN.com (on Twitter). Teams are not required to allow position coaches to interview for coordinator gigs and the Eagles exercised their right to block the Jets’ inquiry on DeFilippo, even though it is a clear promotion. 
DeFilippo was not the only candidate on the Jets’ list, but he was certainly amongst the early favorites to land the job. The Jets have also been linked to former Chargers head coach Mike McCoy and today’s development could push them further in that direction.
I would speculate that the Eagles are shielding DeFilippo in the event that current offensive coordinator Frank Reich leaves for a head coaching gig. Already, Reich has been connected to the Bills job and there could be more interest coming down the pike. I would also imagine that the Eagles are giving DeFilippo a pay bump to avoid any discontent in 2017.
It’s simple really. Eagles protecting themselves in case Reich gets the Buffalo job. If that happens, Flip is the new OC in Philly. If not, Flip gets a pay raise and a promise not to block any future interview requests.
Good play by the Birds. I thought their offensive plays were very creative this year, too bad a few guys couldn’t catch.
