One thing that you failed to mention is the passing lane that Ponder has to deliver an accurate throw. There are many a couch potato that could throw a football 10-yards to Jennings if given this situation. Keep in mind that Ponder and Jennings are still finding their way, and Jennings has to recognize the linebacker before him and know when to "sit down" on this route, although it looks like the linebacker has his attention turned to Peterson who appears to be emerging from the backfield.
