So if the OL opens a hole for Ronnie Brown, Brown still throws the ball backwards? No, but that doesn't mean the OL is responsible for a stupid play.
That's your logic right now.
That isn't close to making any sense in comparison to what happened and to what Imac is talking about.
It is more like The Oline doesn't make a hold for Brown, instead dont block the NT and while trying to step sideways to avoid the NT he loses control of the ball. Blame goes on the line for not blocking the NT.
