It’s week 15 of the 2015 season. The Bills are hosting the Eagles in what amounts to a must-win game. With the game tied at 20 late in the fourth quarter, Philadelphia faces a third-and-three from its own 41-yard line. As QB Sam Bradford drops back to throw, WR Josh Huff runs a shallow crossing route and collides with Buffalo safety Corey Graham. That contact frees up TE Zach Ertz, who turns a short pass from Bradford into a 41-yard reception.
Both live and on replay, Huff’s move looks like an illegal pick play—offensive pass interference, which comes with a 15-yard penalty, but there is no flag thrown.
