I started a franchise with a power run scheme, which is new for me. I’ve always been a spread team utilizing zone runs, so the only real issue I had running the ball were that on zone plays, linemen frequently double team when they don’t need to and often don’t get to the second level, leaving linebackers completely unblocked. Now running more power plays and such, I’m seeing more of the issues like mentioned, especially what you said.
Someone mentioned earlier that they just target what they see in front of them. I actually had a couple of plays where a pulling guard stopped and tried to block someone behind me. Not very often, but enough to make me think it’s not just a run straight ahead and hit whatever you see.
