I have a suggestion for an additional column that can be added for the lineup builder. I see you have PFF Rush grade for RBs, what if you add a column that calculates the difference between the players rush grade vs the opposing team’s rush def grade. The greater the number in the positive shows a more advantageous matchup for the running back and a negative number or lower number shows a better matchup for the defense in stopping the run. This can be used also for Pass block vs opp pass rush defense as well. Something that has a quick snapshot of areas that can be exposed and useful for deciding what player to add into your lineup. Thanks again for your time!
