I think our thoughts aren't far off from each other. Maybe I am expecting too much for Haarberg to be able to move around in the pocket or scramble to one side and stay looking downfield to find an open receiver. He obviously has issues doing that, so yes, his best option may just be to try and find a lane and run.
The trouble with that is that I don't think Haarberg is very quick. Yes, he's a big and fast guy, especially in the open field, but he doesn't have good and quick feet. He lumbers around on the field. But, that's why the coaches were looking for him to be an H-Back type at the beginning of the season.
