Option routes are very tricky and they require an intelligent quaterback who has great chemistry with his receivers. Some of the best chemistry we've seen in awhile has been the out of nowhere on-the-field relationship between Nick Foles and Riley Cooper.

One thing that Sheil and Tim wrote about back in the offseason was how Kelly, Shurmur, Lazor and Bicknell were planning on addition option routes to the offense . Given the QBs we have had over the better part of the last 15 years, this hasn't been a staple in an Eagles offense for a long time.

As we continue to dive into the Chip Kelly offense we've spent a ton of time talking about the read-option and packaged plays .

Let's take a look at a beautiful option route that led to the most impressive TD of the game on Sunday.

You see here a close up of Riley Cooper matched up against Traemon Williams in the slot:

Williams is in zone coverage and he will pass off Cooper to the deep safety:

Once in the open area Cooper looks to be running a post route. However watch the reaction of the safety:

As the safety jumps to cut off the route, this is where Cooper and Foles are reading the coveage. Cooper makes a razor sharp cut to re-route to the corner where there is no more help:

You can see the safety stumbling on the cut and is taken out of the play. Nick now releases the football:

Check out the separation Cooper has for an an easy TD catch:

This is another powerful option added to Chip Kelly's offense this year. I am not sure how much we've run these this year, and it's tough to see sometimes on film when it is an option route. The dangerous thing about option routes is that they can backfire if the QB and receiver are not on the same page. For example, had Foles decided to fire the slant to Cooper as he decides to cut the route off, the safety is in a position to make an interception. On the flip side, had Cooper continued with the post route, Foles may have thrown it to the corner of the end zone looking like a miscommunication.

Kevin Gilbride's offense with Eli Manning contains a lot of option routes. It's why you often see what appear to be really dumb interception from Eli time-to-time:
