I have done these types of tests before. I believe you will have better luck testing run defense if you evaluate the power move as this is the ability to shed your block, on the defensive line, in a run play. Conversely, finnesse move is the ability to rush the passer. Of course tackling is also a key factor.
During my testing, strength had no significant impact.
I also noticed block shedding was more of an open field ability while power move and finesse move were D-Line abilities.
