No, it's similar to how Garett Nelson was always blamed because he's the only guy who was ever close to the ball. Most of the time when Nelson was blamed, it was an interior lineman or linebacker's fault for not doing their assignment correctly. It's the same thing with Gifford. Gifford has to engage 1 or multiple blockers while being the only guy on the edge. It's not an easy job, especially when the other guys are lazy or doing God knows what and not getting over there to help him.
Sorry man I know what I'm watching.
Has nothing to do with his assignment beyond he shouldn't be in there. Which I attribute to coaching.
