You could also use the Yatzr recruiting tool as a general guideline for position changes. If you use the team analyzer feature, just put the equation for another position next to your actual position (i.e. In the 2nd slot for LB put the DL equation). Obviously your ratings will change once you change positions, but it gives you a quick general idea of what your guy would look like at a different position. Also if you did that, it would show for recruits too, which may or may not be interesting to you.
